Zero prevalence of diabetes in camel milk consuming Raica community of north-west Rajasthan, India.

OBJECTIVES: Preliminary trials reflected the low prevalence of diabetes in Raica community consuming camel milk habitually. Our objective was to describe the prevalence and clinical factors associated with impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and diabetes (DM) among adults (>or=20 years) in large population group. DESIGN: Population based, cross sectional study METHODS: 2099 participants from different villages of north-west Rajasthan were selected using stratified sampling of a representative Raica and non-Raica Community, consuming or not consuming camel milk. Demographic, clinical, anthropometric parameters were obtained and oral glucose tolerance tests were performed in all individuals to diagnose IFG, IGT and DM. Associations were investigated using multivariate logistic regression using SPSS Version 10.0. RESULTS: In the present study, the prevalence of diabetes in Raica community consuming camel milk (RCCM, n=501) was 0%; Raica community not consuming camel milk (RCNCM, n=554) was 0.7%; non-Raica community consuming milk (NRCCM, n=515) was 0.4% and non-Raica community not consuming camel milk (NRCNCM, n=529) was 5.5%. Stepwise logistic regression analysis showed that consumption of camel milk was statistically highly significant as protective factor for diabetes. Multiple logistic regression analysis revealed that camel milk consumption and community factor were associated with decreased prevalence of diabetes. CONCLUSION: Camel milk consumption and lifestyle have definite influence on prevalence of diabetes. Hence, adopting such life pattern may play protective role in preventing diabetes to some extent.

Magnitude of dyslipedemia and its association with micro and macro vascular complications in type 2 diabetes: a hospital based study from Bikaner (Northwest India).

AIM: Type 2 diabetes is not only associated with hyperglycemia but also with disorders of lipid metabolism. The aim of this study was to investigate the association of dyslipedemia with micro and macro vascular complications of diabetes. METHODS: Population based cross sectional study included 4067 diabetic patients who visited hospital during January 2000 to December 2002. Lipid profile was estimated by semi autoanalyser, Retinopathy was assessed by fundoscopy, Nephropathy by microalbuminurea, coronary artery disease (CAD) by electro cardiogram (ECG) changes, peripheral vascular disease (PVD) by doppler study and neuropathy by clinical examinations. The association of dyslipedemia with micro and macro vascular complications was assessed by regression analysis. RESULTS: The prevalence of dyslipedemia is high in diabetic population with high serum cholesterol >240mg/dl was seen in 15%, serum triglycerides >160mg/dl was seen in 42.41%, raised LDL >130mg/dl in 45.26%, VLDL >40mg/dl in 24.09% and low levels of HDL-C <40mg/dl were seen in 52.27%. On regression analysis, CAD had strong correlation with high levels of VLDL (0.76), triglycerides (0.82), LDL (0.23) and low HDL (-0.81). Similar association was seen with PVD. Diabetic retinopathy and nephropathy were found to have significant correlation with low HDL (-0.43) and raised LDL (0.37), respectively. Neuropathy was not found to have any significant correlation with lipid profile abnormalities. CONCLUSION: Lipid profile abnormalities are very common in type 2 diabetes and it has great influence on CAD and PVD. Hence, appropriate preventive and treatment strategies should be considered timely.

The changing spectrum of severe falciparum malaria: a clinical study from Bikaner (northwest India).

BACKGROUND & OBJECTIVES: Recently there were reports from all over India about changing spectrum of clinical presentation of severe malaria. The present study was planned to study the same in the northwest India. METHODS: This prospective study was conducted on patients of severe malaria admitted in a classified malaria ward of a tertiary care hospital in Bikaner, Rajasthan (northwest India) during 1994 and 2001. It included adult patients of both sexes belonging to all age groups. The diagnosis of Plasmodium falciparum was confirmed by demonstrating asexual form of parasites in peripheral blood smear. All patients were treated with i.v./oral quinine. The specific complications were treated by standard WHO protocol. The data for individual complications for both the years were analysed by applying chi-square test. RESULTS: In a prospective study in 1994 the spectrum of complication was dominated by cerebral malaria (25.75%) followed by jaundice (11.47%), bleeding tendencies (9.59%), severe anaemia (5.83%), shock (5.26%), Acute respiratory distress syndrome-ARDS (3.01%), renal failure (2.07%) and hypoglycemia (2.07%) whereas in 2001 it was dominated by jaundice (58.85%) followed by severe anaemia (26.04%), bleeding tendencies (25.52%), shock (10.94%), cerebral malaria (10.94%), renal failure (6.25%), ARDS (2.08%) and hypoglycemia (1.56%). The sharp difference for presence of jaundice and severe anaemia in 2001 and cerebral malaria in 1994 was statistically significant. Similarly, the important cause of mortality in 2001 was multiple organ dysfunction syndrome (71.10%) with predominant presentation of jaundice and renal failure, whereas in 1994, it was cerebral malaria (77.96%). INTERPRETATION & CONCLUSION: The observation of changing spectrum of severe malaria in this study and a significant increase in presentation with jaundice as an important manifestation is highly essential for primary, secondary and tertiary level health care providers for proper diagnosis and management.

A comparative study of regression of jaundice in patients of malaria and acute viral hepatitis.

BACKGROUND & OBJECTIVES: Jaundice is one of the common manifestations of severe malaria in adults. The purpose of this study is to compare the pattern of clinical and biochemical parameters such as serum bilirubin and liver enzyme levels in patients of malaria with jaundice and acute viral hepatitis. METHODOLOGY: The present study was conducted on 34 patients of malaria with jaundice and 15 patients of acute viral hepatitis. Estimation of serum bilirubin, aspartate amino transferase (AST), alanine amino transferase (ALT) and alkaline phosphatase was done daily using standard procedures in malaria patients and weekly in acute viral hepatitis patients. RESULTS: Mean level of serum bilirubin on first day in malaria and acute viral hepatitis patients was 7.07 +/- 3.94 and 10.38 +/- 7.87 mg%, whereas on Day 8 it was 1.19 +/- 1.43 and 7.88 +/- 7.02 mg% respectively. Mean level of AST on Day 1 in malaria and acute viral hepatitis patients was 158.47 +/- 120.35 and 1418.6 +/- 834.11 IU/L, whereas on Day 8 it was 41 +/- 28.33 and 775.3 +/- 399.01 IU/L respectively. Mean level of ALT on Day 1 in malaria and acute viral hepatitis patients was 220.14 +/- 145.61 and 1666.67 +/- 1112.77 IU/L, whereas on Day 8 it was 50.85 +/- 37.31 and 823.8 +/- 475.06 IU/L respectively. Mean level of serum alkaline phosphatase on Day 1 in malaria and acute viral hepatitis patients was 394.74 +/- 267.78 and 513.4 +/- 324.7 IU/L, whereas on Day 8 it was 84.76 +/- 68.50 and 369.27 +/- 207.75 IU/L respectively. INTERPRETATION & CONCLUSION: We observed that resolution of jaundice in malaria took 1-2 weeks in contrast 6 to 8 weeks in viral hepatitis. This difference in duration was statistically significant. Thus, jaundice not resolving in 1-2 weeks time in a patient of malaria requires serious consideration for presence of other concomitant diseases including viral hepatitis.

A double blind, randomised placebo controlled trial of rifampicin with omeprazole in the treatment of human cutaneous leishmaniasis.

BACKGROUND & OBJECTIVES: This study was conducted on 50 patients of Anthroponotic cutaneous leishmaniasis (oriental sore) to assess the efficacy of rifampicin and omeprazole through a double blind, randomised placebo control study. METHODS: The diagnosis of Anthroponotic cutaneous leishmaniasis (ACL) caused by Leishmania tropica was done by demonstration of Leishmania tropica (LT) bodies from the painless, dry ulcerative lesion. Each patient was assessed clinically in the beginning of the study, at the end of 2,4 and 6 weeks and all observations were compared in both the groups. Twenty-five patients received rifampicin with omeprazole (Group A) whereas other 25 patients received placebo (Group B) for a period of six weeks. RESULTS: Altogether 23 cases in group Aand 21 cases in group B completed the study. About 16 (69.7%) cases in group A and 3 (14.29%) cases in group B had complete healing, whereas 3 patients (13.04%) of group A and 4 patients (19.05%) of group B had partial response and 4 patients (17.93%) of group A and 14 patients (66.67%) of group B had no response at the end of study. The difference of two groups was statistically highly significant (p < 0.00025). All patients tolerated the drug and placebo very well and no side effect was reported. INTERPRETATION & CONCLUSION: In our opinion rifampicin and omeprazole is a highly effective, less toxic and cheaper alternative for the management of cutaneous leishmaniasis.

Divalproex sodium in the management of post-herpetic neuralgia: a randomized double-blind placebo-controlled study.

BACKGROUND: Post-herpetic neuralgia is difficult to treat. Divalproex sodium (valproic acid and sodium valproate in molar ratio 1:1) has been used successfully in the management of various painful neuropathies. AIM: To study the effectiveness and safety of divalproex sodium in the management of post-herpetic neuralgia. DESIGN: Randomized double-blind placebo-controlled trial. METHODS: We enrolled 48 consecutively attending out-patients with post-herpetic neuralgia, out of whom three were excluded (two had insufficient pain, one withdrew consent). Quantification of pain was by Short Form-McGill pain questionnaire (SF-MPQ), visual analogue scale (VAS), present pain intensity score (PPI) and 11 point Likert scale (11 PLS) at the beginning of the study, after 2 weeks, 4 weeks and at the end of the study (8 weeks). We also assessed patients' global impression of change by questionnaire at the end of the study. RESULTS: After 8 weeks treatment with 1000 mg/day divalproex sodium, there was significant reduction in pain: SF-MPQ, 20.47 +/- 2.29 to 11.90 +/- 6.52 (p < 0.0001); PPI 4.0 +/- 0.52 to 1.95 +/- 1.29 (p < 0.0001); VAS 70.17 +/- 9.21 to 31.27 +/- 29.74 (p < 0.0001) and 11 PLS 6.97 +/- 0.73 to 3.63 +/- 2.34 (p < 0.0001) in comparison to placebo (means +/- SEM). The 'global impression of change' questionnaire showed much or moderate improvement in pain in 58.2% of patients receiving divalproex vs. 14.8% of those receiving placebo. The drug was well tolerated by all patients, except one who developed severe vertigo after 10 days of treatment. DISCUSSION: Divalproex sodium provides significant pain relief in patients of post-herpetic neuralgia, with very little incidence of adverse reactions. These data provide a basis for longer trials in a larger group of patients.

Sodium valproate for painful diabetic neuropathy: a randomized double-blind placebo-controlled study.

BACKGROUND: Various drugs are effective in the management of painful diabetic neuropathy, but none is completely satisfactory. We previously found sodium valproate to be effective and safe in a short-term study. AIM: To test the effectiveness and safety of sodium valproate in the management of painful diabetic neuropathy over 3 months. DESIGN: Randomized double-blind placebo-controlled study. METHODS: Consecutive attending patients with type 2 diabetes mellitus with painful neuropathy were asked to participate in the trial: 48 agreed. Five were excluded: three with HbA(1c) > 11, one with too low a pain level and one who withdrew consent. The remaining 43 were given either drug (group A) or placebo (group B). Each patient was assessed clinically. Quantitative assessment of pain was done by McGill Pain Questionnaire, Visual Analogue Score and Present Pain Intensity, at the beginning of the study, after 1 month and after 3 months. Motor and sensory nerve conduction velocities were measured initially and after 3 months. Liver function tests and other adverse drug-related effects were assessed periodically. RESULTS: Of the 43 patients, four dropped out: one in group A and three in group B. There was significant improvement in pain score in group A, compared to group B, at 3 months (p < 0.001). Changes in electrophysiological data were not significant. The drug was well-tolerated by all patients, except one, who had raised serum AST and ALT levels after 1 month of treatment, and whose treatment was discontinued. DISCUSSION: Sodium valproate is well-tolerated, and provides significant subjective improvement in painful diabetic neuropathy.

Asymptomatic spinal arachnoiditis in patients with tuberculous meningitis.

Spinal arachnoiditis is one of the common and disabling complication of tuberculous meningitis (TBM). We focused on early diagnosis of spinal arachnoiditis by spinal MRI in asymptomatic patients in whom neurological examination was normal. We studied 16 patients with a diagnosis of probable or highly probable TBM with symptoms for less than 1 month; three had radiological evidence of spinal arachnoiditis. High cerebrospinal fluid protein appeared to be a risk factor for development of spinal arachnoiditis. MRI is sensitive to detect early spinal arachnoiditis. Earlier diagnosis may be helpful in management of spinal arachnoiditis in TBM.

Hepatocyte dysfunction and hepatic encephalopathy in Plasmodium falciparum malaria.

BACKGROUND: According to the WHO, signs of hepatic dysfunction are unusual, and hepatic encephalopathy is never seen in malaria. However, in recent years, isolated cases have been reported from different parts of world. AIM: To identify the evidence for hepatocyte dysfunction and/or encephalopathy in jaundiced patients with falciparum malaria. DESIGN: Prospective observational study. METHODS: We studied 86 adult patients of both sexes who had malaria with jaundice (serum bilirubin > 3 mg%). The main outcome measures were: flapping tremor, deranged psychometric test, level of consciousness, serum bilirubin level, serum aspartate transaminase (AST) and alanine transaminase (ALT) levels, blood ammonia level, viral markers for hepatitis, ultrasonography of liver and gall bladder and electroencephalography (EEG). RESULTS: The range of serum bilirubin was 3-48.2 mg% (mean +/- SD 10.44 +/- 8.71 mg%). The ranges of AST and ALT levels were 40-1120 IU/l (294.47 +/- 250.67 IU/l) and 40-1245 IU/l (371.12 +/- 296.76 IU/l), respectively. Evidence of hepatic encephalopathy was seen in 15 patients. Asterexis was observed in 9 patients, impaired psychometric tests in 12 and altered mental state in 13. Arterial blood ammonia level was 120-427 meq/l (310 +/- 98.39 meq/l). EEG findings included presence of large bilateral synchronous slow waves, pseudo burst suppression and triphasic waves. Four patients died due to multiple organ dysfunction; the others made rapid recoveries. DISCUSSION: There is strong evidence of hepatocyte dysfunction and hepatic encephalopathy in some of these patients, with no obvious non-malarial explanation. Current guidelines may need to be revised.

Pulmonary manifestations in brucellosis: a report on seven cases from Bikaner (north-west India).

OBJECTIVES: Pulmonary manifestations of Brucellosis are rare. We came across seven patients with predominant symptomatology of pulmonary involvement amongst 98 patients of active brucellosis seen in last four years. MATERIAL AND METHODS: The study is related to patients of brucellosis whose principal presenting features were related to respiratory symptom (cough, expectoration, pain in chest and breathlessness) along with fever and other constitutional symptoms. It included seven patients amongst 98 patients of active brucellosis seen during June 1996 to Feb. 2000 at PBM Hospital Bikaner. Diagnosis was confirmed by demonstration of the raised brucella agglutination titre of 1:320 or more in the serum. All patients were treated with rifampicin 900 mg daily and doxycyclin 100 mg twice daily for six week. The treatment was extended for another four weeks in two patients because of persistence of skiagram abnormalities. RESULT: Three patients had abnormality in skiagram chest in the form of pleural effusion, multiple paranchymal opacities and pneumonia. The skiagram chest was normal in remaining four patients. The response of treatment started with 10-15 days and all the patients became symptom-free at the end of six weeks except one patient. Skiagram chest at this time was normal in patients of pleural effusion but there was persistence of haziness and few opacities in other two patients. Follow up skiagram chest at the end of six months and twelve months was normal in all patients except calcified opacity in one patient. There was no evidence of relapse in any patient at the end of one year follow up. Liver function tests remained within normal range and no drug toxicity was observed. CONCLUSION: Pulmonary manifestations of brucellosis are rare. Treatment with rifampicin and doxycylin showed marked clinical and radiological improvement. All patients were completely disease-free at the end of one year follow up.

Malarial hepatitis.

AIMS AND OBJECTIVE: To study the clinical, biochemical and histopathological changes in the liver of patients of Plasmodium falciparum malaria with jaundice. MATERIAL AND METHOD: This study was conducted on 50 PBF confirmed cases of Plasmodium falciparum malaria with jaundice. Detailed history, clinical examination, biochemical parameters for liver function test and blood for hepatitis B and C was done in all patients. Liver biopsy was done for detailed histopathological examination in all the 20 patients having serum bilirubin between 3 to 10 mg%. All patients were treated by IV/oral quinine using standard regimen. RESULTS: Age of the patient was ranging from 15-45 years. All patients had jaundice, 70% had pallor, 56% had splenomegaly, 48% had hepatomegaly and 24% of cases had coma. Based on serum bilirubin level, the patients were categorized in group A (18 patients, serum bilirubin < 3 mg%), in group B (20 patients, serum bilirubin 3-10 mg%) and in group C (12 patients, serum bilirubin >10 mg%). Histopathological examination done in all the 20 patients of group B, showed evidence of swollen hepatocytes (100%), malarial pigment deposition (75%), inflammatory infiltrates (60%), congestion of hepatocyte (50%) alongwith centrizonal necrosis in 25% of cases. CONCLUSION: The evidence of predominant conjugated hyperbilirubinemia, increased levels of AST and ALT along with evidence of hepatocellular necrosis in histopathological examination are strong evidence of gross hepatocytic dysfunction in patients of Plasmodium falciparum malaria with jaundice. Therefore the term malarial hepatitis should not be taken as a misnomer.

Sodium valproate in the management of painful neuropathy in type 2 diabetes - a randomized placebo controlled study.

OBJECTIVE: To study the effectiveness and safety aspects of sodium valproate in the management of painful neuropathy in patients of type 2 diabetes mellitus. MATERIAL AND METHODS: A randomized double-blind placebo controlled trial of sodium valproate was done in type 2 diabetic patients to assess its efficacy and safety in the management of painful neuropathy. We screened 60 patients but eight patients could not complete the study; hence, the present study was done on 52 patients. Each patient was assessed by clinical examination, pain score by short form of the McGill pain questionnaire (SF-MPQ) and electrophysiological examination, which included motor and sensory nerve conduction velocity, amplitude and H-reflex initially and at the end of 1 month of treatment. RESULTS: Significant improvement was noticed in the pain score of patients receiving sodium valproate in comparison to patients receiving placebo at the end of 1 month (P < 0.05). The changes in electrophysiological data were not significant. The drug was well tolerated by all patients except one who developed a raised aspartate transaminase (AST)/alanine transaminase (ALT) level after 15 days of treatment. CONCLUSION: Sodium valproate is a well-tolerated drug and provides significant subjective improvement in painful diabetic neuropathy. These data provide a basis for future trials of longer duration in a larger group of patients.

A randomized placebo controlled trial of Inolter (herbal product) in the treatment of type 2 diabetes.

OBJECTIVE: To evaluate the safety and effectiveness of Inolter in achieving glycemic control and changes in lipid profile of newly diagnosed type 2 diabetics. MATERIAL AND METHODS STUDY DESIGN: A randomized, placebo-controlled double blind. Sixty newly diagnosed patients of type-2 diabetes were randomized. Of these, 30 were put on Inolter monotherapy and 30 patients on placebo. Efficacy of Inolter was determined by observing glycemic control by estimating glycosylated haemoglobin (HbA1c) and fasting blood sugar (FBS), alteration of lipid profile by serum cholesterol, LDL, VLDL, HDL and triglycerides. STATISTICAL METHODS: Student's unpaired 't' test. RESULTS: Patients compliance was satisfactory and no adverse effects were observed. Better hypoglycemic effect was observed with Inolter both respect to fasting blood sugar (mean 65.4 +/- 63.72 mg/dl) compared to placebo (mean 26.45 +/- 38.3 mg/dl) (p < 0.001). The mean change, with Inolter, in serum cholesterol (21.33 +/- 26.05 mg/dl), serum triglyceride (30.36 +/- 32.62 mg/dl), VLDL (8.85 +/- 3.25 mg/dl), LDL (10.00 +/- 4.48 mg/dl) and HDL (-2.33 +/- 5.66 mg/dl) was also significantly different (p < 0.001) from those given placebo, where it was 15.7 +/- 20.14 mg/dl, 8.70 +/- 13.24, 0.10 +/- 4.10 mg/dl, -0.70 +/- 4.58 mg/dl and 0.65 +/- 0.00 mg/dl, respectively. CONCLUSION: Inolter appears to be an useful adjunctive therapy to exercise and diet control in newly diagnosed type 2 diabetes mellitus.

Cerebral malaria in Indian adults: a prospective study of 441 patients from Bikaner, north-west India.

AIMS OF THE STUDY: As per WHO (1993) the assessment and analysis of local problems and an appropriate epidemiological information system is an essential part of a control programme before embarking any control activity. METHODOLOGY: Four hundred and fourty one (441) adults of strictly defined admitted cerebral malaria patients were studied. Detailed clinical/neurological examination was done at the time of admission, daily thereafter, at the time of regaining consciousness, at the time of discharge and at weekly intervals in those having neurological sequelae. All patients were treated by i.v./oral quinine and specific syndromes were managed according to WHO guidelines. RESULTS: Apart from fever and unconsciousness in all the patients, other features were convulsion (21.31%), neck rigidity (19%), psychosis (5.21%), conjugate deviation of eyes (2.26%), extrapyramidal rigidity (2.25%), trismus (1.31%), decorticate rigidity (1.13%) and decerebrate rigidity (0.90%). One hundred forty five (32.87%) patients expired and mortality was highest in pregnant ladies (39.28%). The important neurological sequelae in survivors were psychosis in 15 (5.06%), cerebellar ataxia in 14 (4.72%), hemiplegia in five (1.68%), extrapyramidal rigidity (EPR) in four (1.35%), peripheral neuropathy in three (1.01%), EPR with trismus in one (0.33%) and isolated sixth nerve palsy in one (0.33%) patients and all showed complete recovery in further follow up. CONCLUSION: The important observations of this study were stormy presentation, increased incidence of haemoglobinuria and jaundice, presence of neck rigidity, no prognostic relation to fundus abnormalities and high incidence of cerebellar ataxia and psychosis as neurological sequelae in survivors. Knowledge of self-limiting course of neurological sequelae may be helpful in reducing economic strain of expensive investigations and treatment.
