Statins can reduce the risk of stroke in at-risk populations and improve survival after acute ischemic stroke (AIS) among patients with previous statin use. This study aimed to investigate the impact of statin use before AIS onset on in-hospital mortality and identify the factors related to in-hospital mortality among patients with and without previous statin use. A retrospective cohort study of all patients with AIS attending hospital from June 1, 2008 to December 31, 2008. Data were collected from medical records including demographic information, diagnostic information, risk factors, previous statin use, and vital discharge status. Chi-square, Fisher's exact tests, student's t-test, and Mann-Whitney U test, whatever appropriate, were used to test the significance between the variables, and multiple logistic regression was used to identify factors associated with in-hospital mortality. Altogether, 386 patients with AIS were studied, of which 113 (29.3%) had a documented previous statin use. A total of 62 (16.1%) patients with AIS died in hospital. In-hospital mortality was significantly lower among previous statin users (P = 0.013). The presence of atrial fibrillation (AF) increased in-hospital mortality among patients with or without previous statin use. The independent predictors for in-hospital mortality among AIS patients without previous statin use were the presence of diabetes mellitus (P = 0.047), AF (P = 0.045), and renal impairment (P < 0.001). The prophylactic administration of statins significantly reduces post-AIS in-hospital mortality. Furthermore, the identification of predictors of in-hospital mortality might reduce death rates and enhance the application of specific therapeutic and management strategies to patients at a high risk of dying.

Introduction: Although the benefit of low protein diet (LPD) on chronic kidney disease (CKD) progression is well documented, patients’ adherence remains as the main challenge. Therefore, this study sought to identify adherence towards LPD among CKD patients and determine possible associating factors. Methods: This cross-sectional study was done at the Hospital Pakar Sultanah Fatimah in Muar, Johor, among stage III to V CKD patients. Three-day dietary recalls were used to quantify dietary energy (DEI) and protein intake (DPI). Factors investigated include socio-demo- graphic characteristics, medical history, anthropometry and body composition measurements, dietary knowledge, appetite level, handgrip strength, perceived stress, and health locus of control. Associating variables were analysed with logistic regression analysis. Results: The final analysis included 113 patients (54% male) with a mean estimated glomerular filtration rate of 17.5±11.2mL/min/1.73m2 and the average age of 56.3±12.8 years. Mean DEI and DPI were 22.4±5.9kcal/kg/day and 0.83±0.28g/kg/day, respectively. Only 34.5% of patients adhere to the LPD diet with 59% exceeding the DPI recommendation. Poorer LPD adherence was associated with longer duration of hospitaliza- tion (OR 0.707, 95%CI 0.50-1.00, p=0.048), higher energy intake (OR 0.744, 95%CI 0.65-0.85, p

The aim of this study was to compare 6% hydroxyethyl starch 130/0.4 with 4% succinylated gelatin for priming the cardiopulmonary bypass circuit and as volume replacement in patients undergoing coronary artery bypass, in terms of postoperative bleeding, blood transfusion requirements, renal function, and outcome after surgery. Forty-five patients received 6% hydroxyethyl starch 130/0.4 (Voluven) and another 45 were given 4% succinylated gelatin (Gelofusine) as the priming solution for the cardiopulmonary bypass circuit as well as for volume replacement. Postoperative bleeding was quantified from the hourly chest drainage in the first 4 h and at 24 h postoperatively. The baseline characteristics of both groups were similar. In the hydroxyethyl starch group, the total amount of colloid used was 1.9 +/- 1.0 L, while the gelatin group had 2.0 +/- 0.7 L. There was no significant difference in hourly chest drainage between groups. Blood transfusion requirements, estimated glomerular filtration rate, extubation time, intensive care unit and hospital stay were similar in both groups. It was concluded that 6% hydroxyethyl starch 130/0.4 is a safe alternative colloid for priming the cardiopulmonary bypass circuit and volume replacement in patients undergoing coronary artery bypass surgery.

Chronic Kidney Disease has become a public health problem, imposing heath, social and human cost on societies worldwide. Chronic Kidney Disease remains asymptomatic till late stage when intervention cannot stop the progression of the disease. Therefore, there is an urgent need to detect the disease early. Despite the high prevalence of Chronic Kidney Disease in Malaysia, screening is still lacking behind. This review discusses the strengths and limitations of current screening methods for Chronic Kidney Disease from a Malaysian point of view. Diabetic Kidney Disease was chosen as focal point as Diabetes is the leading cause of Chronic Kidney Disease in Malaysia. Screening for Chronic Kidney Disease in Malaysia includes a urine test for albuminuria and a blood test for serum creatinine. Recent literature indicates that albuminuria is not always present in Diabetic Kidney Disease patients and serum creatinine is only raised after substantial kidney damage has occurred. Recently, cystatin C was proposed as a potential marker for kidney disease but this has not been studied thoroughly in Malaysia. Glomerular Filtration Rate is the best method for measuring kidney function and is widely estimated using the Modification of Diet for Renal Disease equation. Another equation, the Chronic Kidney Disease Epidemiology Collaboration Creatinine equation was introduced in 2009. The new equation retained the precision and accuracy of the Modification of Diet for Renal Disease equation at GFR < 60ml/min/1.73m2, showed less bias and improved precision at GFR>60ml/min/1.73m2. In Asian countries, adding an ethnic coefficient to the equation enhanced its performance. In Malaysia, a multi-ethnic Asian population, the Chronic Kidney Disease Epidemiology Collaboration equation should be validated and the Glomerular Filtration Rate should be reported whenever serum creatinine is ordered. Reporting estimated Glomerular Filtration Rate will help diagnose patients who would have been otherwise missed if only albuminuria and serum creatinine are measured.

Clinical manifestations of sickle cell disease (SCD) arise from the tendency of the sickle haemoglobin to polymerize and deform red blood cells into the characteristic sickle shape. Sickle cell crisis is a devastating complication that may occur in patients with SCD. If not managed properly permanent organ damage and even death may be the final outcome. A case of a 32-year-old Nigerian lady, Gravida 1 Para 0 in her first trimester, with SCD who developed signs and symptoms of delayed haemolytic transfusion reaction after receiving packed red cell transfusion is demonstrated. Multiple red cell alloantibodies were detected in the patient's plasma; anti-Fy a, anti-Jk b and anti-E. The patient miscarriaged and succumbed to complications of hyperhaemolysis with delayed haemolytic transfusion reaction, acute chest syndrome and renal failure. There is an urgent need for mandatory red cell antibody screen and identification especially in high-risk cases. Prevention of alloimmunization by supplying phenotype-specific red cells is also required.

Fulltext Association between health-related quality of life and psychological distress at different stages of chronic kidney disease

Norhayati Ibrahim, Rafidah Aini Pakri Mohamed, Sharlene Teo, Normah Che In, Abdul Halim Abdul Gafor, Rozmi Ismail, et al.

Sains Malaysiana, 2016;45(5):753-759.

The prevalence of chronic kidney disease (CKD) have increased and become one of the major public health concerns
worldwide including Malaysia. Previous studies on CKD generally focused on patients who were already undergoing
dialysis treatment; however, studies investigating the stresses experienced by pre-dialysis CKD patients were limited. This
study aimed to examine the prevalence of psychological distress and their association with the Health Related Quality
of Life (HRQoL) during the different stages of CKD. This cross-sectional study involved 200 pre-dialysis patients from
stages 3 to 5, who were recruited from the Nephrology Clinic at the National University of Malaysia Medical Centre
(UKMMC). The instruments used in this study were the Short Form 36 (measuring HRQoL) and Hospital Anxiety and
Depression Scale (HADS) to measure the psychological distress. The results showed that the prevalence of depression
and anxiety increased proportionally with the CKD stages. The HRQoL sub-component scores declined as the CKD stages
increased except for social functioning. An impaired HRQoL was associated with depression and anxiety in the CKD
patients. The results suggested that it is very important to manage kidney disease at an early stage and that a healthier
lifestyle is adopted.

Fulltext A population-based study measuring the prevalence of chronic kidney disease among adults in West Malaysia

Hooi LS, Ong LM, Ahmad G, Bavanandan S, Ahmad NA, Naidu BM, et al.

Kidney Int, 2013 Nov;84(5):1034-40.
PMID: 23760287 DOI: 10.1038/ki.2013.220

In this population-based study, we determine the prevalence of chronic kidney disease in West Malaysia in order to have accurate information for health-care planning. A sample of 876 individuals, representative of 15,147 respondents from the National Health and Morbidity Survey 2011, of the noninstitutionalized adult population (over 18 years old) in West Malaysia was studied. We measured the estimated glomerular filtration rate (eGFR) (CKD-EPI equation); albuminuria and stages of chronic kidney disease were derived from calibrated serum creatinine, age, gender and early morning urine albumin creatinine ratio. The prevalence of chronic kidney disease in this group was 9.07%. An estimated 4.16% had stage 1 chronic kidney disease (eGFR >90 ml/min per 1.73 m(2) and persistent albuminuria), 2.05% had stage 2 (eGFR 60-89 ml/min per 1.73 m(2) and persistent albuminuria), 2.26% had stage 3 (eGFR 30-59 ml/min per 1.73 m(2)), 0.24% had stage 4 (eGFR 15-29 ml/min per 1.73 m(2)), and 0.36% had stage 5 chronic kidney disease (eGFR <15 ml/min per 1.73 m(2)). Only 4% of respondents with chronic kidney disease were aware of their diagnosis. Risk factors included increased age, diabetes, and hypertension. Thus, chronic kidney disease in West Malaysia is common and, therefore, warrants early detection and treatment in order to potentially improve outcome.

Expert opinion on the applicability of dyslipidemia guidelines in Asia and the Middle East

Alshamiri M, Ghanaim MMA, Barter P, Chang KC, Li JJ, Matawaran BJ, et al.

PMID: 30050317 DOI: 10.2147/IJGM.S160555

Cardiovascular disease (CVD) is a growing burden across the world. In Asia and the Middle East, in particular, CVD is among the most prevalent and debilitating diseases. Dyslipidemia is an important factor in the development of atherosclerosis and associated cardiovascular events, and so effective management strategies are critical to reducing overall cardiovascular risk. Multiple dyslipidemia guidelines have been developed by international bodies such as the European Society of Cardiology/European Atherosclerosis Society and the American College of Cardiology/American Heart Association, which all have similarities in practice recommendations for the optimal management of dyslipidemia. However, they differ in certain aspects including pharmacological treatment, lifestyle modification and the target levels used for low-density lipoprotein cholesterol. The evidence behind these guidelines is generally based on data from Western populations, and their applicability to people in Asia and the Middle East is largely untested. As a result, practitioners within Asia and the Middle East continue to rely on international evidence despite population differences in lipid phenotypes and CVD risk factors. An expert panel was convened to review the international guidelines commonly used in Asia and the Middle East and determine their applicability to clinical practice in the region, with specific recommendations, or considerations, provided where current guideline recommendations differ from local practice. Herein, we describe the heterogeneous approaches and application of current guidelines used to manage dyslipidemia in Asia and the Middle East. We provide consensus management recommendations to cover different patient scenarios, including primary prevention, elderly, chronic kidney disease, type 2 diabetes, documented CVD, acute coronary syndromes and family history of ischemic heart disease. Moreover, we advocate for countries within the Asian and Middle East regions to continue to develop guidelines that are appropriate for the local population.

Risk factors for lower extremity amputation among patients with diabetes in Singapore

Yang Y, Østbye T, Tan SB, Abdul Salam ZH, Ong BC, Yang KS

J Diabetes Complications, 2011 Nov-Dec;25(6):382-6.
PMID: 21983153 DOI: 10.1016/j.jdiacomp.2011.08.002

BACKGROUND:
Among other risk factors, renal disease and ethnicity have been associated with diabetic lower extremity amputation (LEA) in Western populations. However, little is known about risk factors for LEA among Asian patients.

OBJECTIVE:
The objective was to assess the proportion of hospitalized patients with diabetes who have a LEA among all hospital patients with diabetes mellitus (DM) and to investigate risk factors for diabetic LEA (especially renal disease and ethnicity) using hospital discharge database.

METHOD:
A retrospective study of hospital discharge database (2004-2009) was performed to identify patients with DM, LEA and renal disease using the International Statistical Classification of Diseases and Related Health Problems, Ninth Revision, Australian Modification codes.

RESULTS:
Of 44 917 hospitalized patients with DM during the 6 years, 7312 (16.3%) patients had renal disease, and 1457 (3.2%) patients had LEA. DM patients with renal disease had significant higher rates of LEA (7.1%) compared to DM patients without renal disease (2.5%, P < .001). The differences were present for foot (2.7% vs. 1.2%), ankle or leg (2.8% vs. 0.9%), and knee or above amputation (1.6% vs. 0.4%, all Prenal disease and ethnicity were significant predictors of diabetic LEA (renal disease: odds ratio 3.2, 95% confidence interval 2.8-3.6; ethnicity: odds ratio, 1.6, Malays vs. Chinese, P < .001; 1.0, Indians vs. Chinese, P = .784) after adjustment for age, gender, and year of discharge.

CONCLUSION:
DM patients with renal disease and Malay ethnicity had higher rates of LEA in this Asian patient population. Malay patients with DM and diabetic patients with renal disease should be considered as high-risk groups for LEA and therefore screened and monitored systematically.

PMID: 25045706 DOI: 10.1155/2014/823879

The current study evaluates the impact of high fructose feeding in rat model of gentamicin induced nephrotoxicity. Sprague-Dawley rats weighing 180-200 g were randomized into four groups; (C) received standard rodents chow with free access to ad libitum drinking water for 8 weeks and was considered as control, (F) received standard rodents chow with free access to drinking water supplemented with 20% (W/V) fructose for the same abovementioned period, (FG) was fed as group F and was given 80 mg/kg (body weight)/day gentamicin sulphate intraperitoneally during the last 20 days of the feeding period, and (G) was given gentamicin as above and fed as group C. Renal function was assessed at the end of the treatment period through measuring serum creatinine, uric acid and albumin, creatinine clearance, absolute and fractional excretion of both sodium and potassium, twenty-four-hour urinary excretion of albumin, and renal histology. For metabolic syndrome assessment, fasting plasma glucose and insulin were measured and oral glucose tolerance test was performed throughout the treatment period. Results showed that gentamicin enhances progression of fructose induced metabolic syndrome. On the other hand, fructose pretreatment before gentamicin injection produced a comparable degree of renal dysfunction to those which were given fructose-free water but the picture of nephrotoxicity was somewhat altered as it was characterized by higher extent of glomerular congestion and protein urea. Overall, more vigilance is required when nephrotoxic drugs are prescribed for patients with fructose induced metabolic syndrome.

Fucoidan Ameliorates Renal Injury-Related Calcium-Phosphorus Metabolic Disorder and Bone Abnormality in the CKD-MBD Model Rats by Targeting FGF23-Klotho Signaling Axis

Liu BH, Chong FL, Yuan CC, Liu YL, Yang HM, Wang WW, et al.

Front Pharmacol, 2020;11:586725.
PMID: 33708111 DOI: 10.3389/fphar.2020.586725

Background: Recently, chronic kidney disease (CKD)-mineral and bone disorder (MBD) has become one of common complications occurring in CKD patients. Therefore, development of a new treatment for CKD-MBD is very important in the clinic. In China, Fucoidan (FPS), a natural compound of Laminaria japonica has been frequently used to improve renal dysfunction in CKD. However, it remains elusive whether FPS can ameliorate CKD-MBD. FGF23-Klotho signaling axis is reported to be useful for regulating mineral and bone metabolic disorder in CKD-MBD. This study thereby aimed to clarify therapeutic effects of FPS in the CKD-MBD model rats and its underlying mechanisms in vivo and in vitro, compared to Calcitriol (CTR). Methods: All male rats were divided into four groups: Sham, CKD-MBD, FPS and CTR. The CKD-MBD rat models were induced by adenine administration and uninephrectomy, and received either FPS or CTR or vehicle after induction of renal injury for 21 days. The changes in parameters related to renal dysfunction and renal tubulointerstitial damage, calcium-phosphorus metabolic disorder and bone lesion were analyzed, respectively. Furthermore, at sacrifice, the kidneys and bone were isolated for histomorphometry, immunohistochemistry and Western blot. In vitro, the murine NRK-52E cells were used to investigate regulative actions of FPS or CTR on FGF23-Klotho signaling axis, ERK1/2-SGK1-NHERF-1-NaPi-2a pathway and Klotho deficiency. Results: Using the modified CKD-MBD rat model and the cultured NRK-52E cells, we indicated that FPS and CTR alleviated renal dysfunction and renal tubulointerstitial damage, improved calcium-phosphorus metabolic disorder and bone lesion, and regulated FGF23-Klotho signaling axis and ERK1/2-SGK1-NHERF-1-NaPi-2a pathway in the kidney. In addition, using the shRNA-Klotho plasmid-transfected cells, we also detected, FPS accurately activated ERK1/2-SGK1-NHERF-1-NaPi-2a pathway through Klotho loss reversal. Conclusion: In this study, we emphatically demonstrated that FPS, a natural anti-renal dysfunction drug, similar to CTR, improves renal injury-related calcium-phosphorus metabolic disorder and bone abnormality in the CKD-MBD model rats. More importantly, we firstly found that beneficial effects in vivo and in vitro of FPS on phosphorus reabsorption are closely associated with regulation of FGF23-Klotho signaling axis and ERK1/2-SGK1-NHERF-1-NaPi-2a pathway in the kidney. This study provided pharmacological evidences that FPS directly contributes to the treatment of CKD-MBD.

Proteomics analysis of blood plasma in HIV-infected patients with chronic kidney disease

Lavinya AA, Lee CS, Hashim OH, Azwa I, Rajasuriar R, Lim SK, et al.

Clin Biochem, 2019 Nov;73:90-97.
PMID: 31401122 DOI: 10.1016/j.clinbiochem.2019.08.006

BACKGROUND: Patients treated for human immunodeficiency virus (HIV) infection are prone to developing chronic kidney disease (CKD). Current methods used in assessing kidney function suffer inaccuracy in HIV-infected patients. This study aims to identify biomarkers that could complement existing methods of kidney assessment among HIV-infected subjects.
METHODS: Plasma protein profiling was performed for HIV patients with CKD presented with negative/trace proteinuria (non-proteinuric) (n = 8) and their matched non-CKD controls, using two-dimensional gel electrophoresis (2DE); selected protein candidates were identified using mass spectrometry. Subsequently, altered plasma abundance of protein candidates were verified using Western blotting in HIV-infected subjects with non-proteinuric CKD (n = 8), proteinuric CKD (n = 5), and their matched non-CKD controls, as well as in HIV-uninfected subjects with impaired kidney function (n = 3) and their matched controls.
RESULTS: Analysis of 2DE found significantly altered abundance of five protein candidates between HIV-infected patients with non-proteinuric CKD and without CKD: alpha-1-microglobulin (A1M), serum albumin (ALB), zinc-alpha-2-glycoprotein (AZGP1), haptoglobin (HP), and retinol binding protein (RBP4). Western blotting showed an increased abundance of A1M and HP in HIV-infected patients with non-proteinuric CKD compared to their non-CKD controls, whereas A1M, AZGP1, and RBP4 were significantly increased in HIV-infected patients with proteinuric CKD compared to their non-CKD controls. Such pattern was not found in HIV-uninfected subjects with impaired kidney function.
CONCLUSION: The data suggests four proteins that may be used as biomarkers of CKD in HIV-infected patients. Further validation in a larger cohort of HIV-infected patients is necessary for assessing the clinical use of these proposed biomarkers for CKD.

Tranexamic acid (TXA) is an antifibrinolytic agent commonly used to achieve hemostasis. However, there have been a few case reports suggesting that high-dose intravenous TXA has epileptogenic property. In patients with renal impairment, even administering the usual recommended dose of TXA can induce seizure episodes. We present here a patient on hemodialysis who developed seizures after receiving two doses of TXA over 5 h period.

Fulltext Causes of low HbA1c in Malaysian university hospital

Sthaneshwar P, Vethakkan SR, Wong CW

Med J Malaysia, 2014 Aug;69(4):175-7.
PMID: 25500845 MyJurnal

INTRODUCTION: Glycohemoglobin (HbA1c) most accurately reflects the previous two to three months of glycaemic control. HbA1c should be measured regularly in all patients with diabetes, and values should be maintained below 7% to prevent the risk of chronic complications. Apart from the genetic variants of haemoglobins many other conditions also known to affect HbA1c measurements. In this study we evaluated the conditions that cause low HbA1c results.

METHODS AND MATERIALS: The data was collected retrospectively HbA1c was measured in our laboratory by Biorad Variant II turbo 2.0. The method is based on chromatographic separation of HbA1c on a cation exchange cartridge. This method has been certified by National Glycohemoglobin Standardization Programme (NGSP). 58437 requests were received in a period of one year (January to December 2011). Medical records were reviewed to identify the conditions that might be associated with these low values.

RESULTS: Among 58437 samples analysed, 53 patients had HbA1c levels < 4.0%. Fourteen patients had haemoglobinopathy. In 34 patients without Hb variants had conditions such as chronic liver disease, chronic kidney disease, haemolytic anaemia, pregnancy, and anaemia of chronic disease. Five non-pregnant individuals who were screened for diabetes mellitus had HbA1c levels < 4%.

CONCLUSION: Our study underscores the importance of that both laboratories and the physicians should be aware of the factors that can influence the HbA1c results. The haematological status should be taken into consideration for proper interpretation of HbA1c results.

We reported a case of a young female patient presented with sepsis and diagnosed with melioidosis and systemic lupus erythematosus (SLE) within the same admission. She presented with 1-week history of productive cough, progressive dyspnoea together with prolonged fever, arthralgia, rashes and oral ulcers. She had septicemic shock, respiratory failure requiring intubation and ventilation in intensive care unit and subsequently developed acute renal failure requiring haemodialysis. Antibiotics and immunosuppressive treatment including low-dose intravenous cyclophosphamide were commenced. She had a remarkable recovery and was discharged after 6 weeks. There was no evidence of active SLE or relapse of melioidosis during clinic follow-ups.

PMID: 31398154

OBJECTIVE: Introduction: Vascular endothelium function interruption has the main role among mechanisms of development and progression of chronic kidney disease. In numerous experimental and clinical studies, it was proved that activated vascular endothelium is a structural and functional unit that matches processes of inflammation with intravascular coagulation, fibrinolysis and haemorheological disorders. The aim: To identify special features of endothelium morphological structure in kidney vessels, coronary arteries and aorta during chronic kidney disease.
PATIENTS AND METHODS: Materials and methods: Based on autopsy materials, we conducted a morphological study of patients (n = 20) aged 45 to 55 years who were observed in cardiac and neurological hospitals for 5-7 years. We removed kidney, heart and aorta samples from patients. For the study, a histological and immunohistochemical methods were used.
RESULTS: Results and conclusions: Morphological study of vessels endothelium of kidneys, heart and aorta demonstrated that in the majority of observations intima underwentprofound pathological changes, manifested by different degrees of disorganization of endothelial lining and violations of structural and functional organization of the endotheliocytes, subendothelial layer, basal membrane. These pathological processes in all cases had similar features with the development of immune inflammation. Inflammatory infiltration was represented by macrophages, mast cells, plasma cells. Biological mediators of the presented cells can aggravate the damage to endothelial cells. Indirect signs of low ability to restore the structure of the vessel wall and endothelial lining may be a weak expression of the VEGF and bcl-2 vascular endothelial growth factor.

PMID: 30263991 DOI: 10.21037/acr.2017.09.05

Pleural effusion is a common encounter in renal failure patients and frequently possess a diagnostic challenge to clinician especially when it was exudative. Fortunately, transudative pleural effusion secondary to fluid overload remains the commonest cause of pleural effusion in haemodialysis patients. Frequent thoracocentesis enhance pleural inflammation and potentially complicate further this challenging clinical presentation. We report a middle-aged gentleman with advanced chronic kidney disease presented with dyspnea and new right upper lobe consolidation on chest roentograph. He had a history of recurrent bilateral pleural effusion secondary to fluid overload and hence multiple attempts of thoracocentesis were performed. Medical thoracoscopy performed previously yielded non-specific pleuritis. Flexible bronchoscopy demonstrates normal airway with negative microbiological studies. Computed tomography (CT) of the thorax shown a loculated hypodense pleural effusion at the apical region of the right upper lobe. Ultrasound guided thoracocentesis anteriorly yield 400 mL of clear straw color fluid which was transudative by Light's criteria. Post tapping chest X-ray shown complete resolution of right upper lobe consolidation and patient reports immediate relieve of dyspnea. Patient was started on regular effective haemodialysis and pleural effusion did not recur during follow up. Loculated pleural effusion masquerading as mediastinal tumour had been reported but pleural effusion that conformed to the contour of a lung lobe is rare. This case highlights the atypical but unique presentation of a transudative pleural effusion and demonstrates the risk of repeated thoracocentesis complicating a simple clinical presentation.

Leptospirosis has a wide range of presentation which ranges from mild flu-like symptoms, to severe form including renal failure, liver failure, and hemorrhage. Pulmonary involvement can progress from subtle clinical features to life threatening pulmonary hemorrhage and acute respiratory distress syndrome. Although benefits of corticosteroids in adult respiratory distress syndrome have been proven and accepted, evidence for use of corticosteroids in pulmonary leptospirosis is still limited. Given the vasculitic nature of severe leptospirosis, it has been proposed that addition of intravenous corticosteroid therapy, particularly in cases of pulmonary involvement is beneficial. We report a case of leptospirosis with suspected pulmonary hemorrhage which deteriorates after a few days of admission in our tertiary hospital. We have demonstrated that the prescription of a lower dose of corticosteroid than what was widely reported in the literature can equally led to a satisfactory recovery of the pulmonary hemorrhage.
