The non-peptide angiotensin II (AII) receptor antagonists are a new class of compounds that are continuing to be developed as therapeutic agents for the treatment of hypertension, heart failure (HF) and chronic renal disease (CRD). Several of these compounds are currently available for therapeutic use in the USA and the European community with several more in clinical trials and in development. Compounds in this new class are as effective as angiotensin converting enzyme (ACE) inhibitors in treating hypertensive patients and appeared to have a similar therapeutic profile to ACE inhibitors in patients with HF and CRD. One clinical advantage of the AII receptor antagonists over ACE inhibitors is an improved side-effect profile with the absence of the persistent dry cough associated with ACE inhibitor therapy. To date, it is clear that the AII receptor antagonists are effective antihypertensive agents. Clinical trials are currently in progress to determine the therapeutic efficacy of these drugs in the treatment of HF and progressive renal disease.

This study was designed to compare the short-term (1-y) tolerability and antiproteinuric efficacy of enalapril and valsartan in patients with type 2 diabetes. Forty-two patients with normal renal function or early-stage nephropathy were recruited in Hong Kong and randomized to valsartan 80 mg/day or enalapril 5 mg/day; the doses were increased to 160 mg and 10 mg daily, respectively, as tolerated. Early-morning urine was analyzed for albumin and creatinine and 24-hour urinary albumin excretion at baseline and 1 year after therapy began. Twenty-two patients were randomized to valsartan and 20 to enalapril. The 2 treatment groups were similar in terms of age, sex distribution, and duration of diabetes or hypertension. Blood pressure decreased to a similar extent (-2.5% to -5.0%) with each drug. Similarly, the 24-hour urinary albumin excretion decreased by 5% to 6% with each drug. The albumin-creatinine ratio in early-morning urine samples and plasma creatinine levels decreased in the valsartan group and increased in the enalapril group, but the difference was not significant. Plasma potassium levels were stable in both groups at the end of study. Cough was reported by 7 (35%) patients receiving enalapril and none of those receiving valsartan (P=.003). In conclusion, enalapril and valsartan both reduced blood pressure and albuminuria to a similar extent with 1 year of therapy in Chinese patients with type 2 diabetes and normal renal function or early-stage nephropathy. Fewer adverse events were reported with valsartan, but both drugs appear to be relatively safe.

Tracheobronchomegaly, also called Mounier-Kuhn syndrome, consists in dilatation of the trachea and major bronchi because of atrophy or absence of their elastic fibers and smooth muscle cells. Standard chest radiography often does not permit diagnosis because only lateral imaging, obtained with X-rays or chest CT scan, shows the true degree of tracheal dilatation. Surgery has no role in tracheomegaly, except for the complications of tracheal stenosis or pneumothorax. The present work reports cadaveric renal transplantation in a 43-year-old woman affected by end-stage renal disease and suffering from congenital tracheobronchomegaly diagnosed during the first decade of life. No surgical or anesthetic problems were encountered during the immediate perioperative period. The patient did not require pulmonary physiotherapy. Antibiotic prophylaxis was given for 10 days. No pulmonary infection developed, and the patient was discharged from the hospital asymptomatic with normal renal function at 25 days after the transplant. Four months later, the patient experienced bronchitis with cough and fever. Antibiotic therapy was performed with totally resolution of symptoms. At 8 months of follow-up after kidney transplantation, the patient is asymptomatic with normal renal function.

The aim of our paper is to describe an unusual pulmonary toxicity of sirolimus (SRL) in a kidney transplant recipient. We present a 34-year-old woman with a second renal transplantation, complicated with steroid-resistant acute rejection and chronic allograft dysfunction. Two years after initiating SRL, she presented complaints of progressive dyspnoea, nonproductive cough, chest pain and low-grade fever of 1 month duration. She had chronic allograft nephropathy and slight elevation of lactic dehydrogenase levels. After exclusion of common reasons of this condition, a computed tomography (CT) of the thorax and bronchoscopy was performed, revealing ground-glass opacification with polygonal shapes on CT and an opaque appearance with numerous macrophages on bronchoalveolar lavage. The alveolar macrophages stained positive by Periodic acid-Schiff. Diagnosis of pulmonary alveolar proteinosis (PAP) was made and drug-induced toxicity was suspected. SRL was withdrawn with marked improvement in the patients' clinical and radiological status. PAP resolved within 3 months without further therapy. PAP is a very rare complication of SRL therapy with only a few cases described. Withdrawal of SRL with conversion to another immunosuppressant seems to be an appropriate procedure in this condition.

A total of 136 patients, 67 HIV, 69 diabetes mellitus (DM) with or without (+/-) end-stage renal disease (ESRD), were registered for tuberculosis treatment at the National Tuberculosis Center (NTBC) from May to December, 2003. Ages ranged from 21-78 years (median 57.7 years) in TB/DM patients, and 21-62 (mean 37.6 +/- 8.3 years) in TB/HIV patients. TB was significantly found in younger and single HIV patients, but in older and married DM patients (p<0.05). Male patients in both groups were strongly associated with TB, while females more commonly had TB with DM (p<0.05). The majority of these patients were Malays, unemployed, and resided in Kuala Lumpur territory; however, no statistically significant difference was found between the 2 groups. Smoking, IVDUs and hepatitis C virus (HCV) infection were more significantly found in TB/HIV patients and further analysis showed that pulmonary TB was strongly associated with HCV infection in these patients (p<0.05). Pulmonary TB (62; 89.9%) was the most common type found in both groups and was a markedly more common disease location in TB/DM patients, while extrapulmonary TB (21; 31.3%) and miliary TB (14; 21%) were significantly higher in TB/HIV patients. Cough with or without sputum, fever and loss of appetite and/or weight were common clinical presentations in both groups. Nevertheless, fever (54; 80.6%) and lymphadenopathy (17; 25.4%) were significantly related to TB/HIV patients (p<0.05). Interestingly, the presence of BCG vaccination and positive tuberculin skin test were stronger in TB/HIV (27; 40.3%) and TB/DM (20; 29%) patients, respectively (p<0.05). Overall, regular 6-, 9- and 12-months' anti-tubercular therapy (ATT) were routine practice, and EHRZ+B6 was the most common regimen used. The highest percentage of patients with treatment success were in both groups with 6 months' ATT; however, a significantly higher percentage was found in TB/DM (24; 34.8%) than TB/HIV (13; 19.4%) (p<0.05). A success rate of 15 (21.7%) was noted for TB/DM patients with 9 months' ATT, which was similar to both groups with the 12-month regimen. A higher percentage failure rate (lost to follow-up) was seen in TB/HIV (19; 28.4%) patients. Nine patients were reported to have anti-tubercular-drug side-effects, such as drug-induced hepatitis, blurred vision, and skin rash. No cases of drug resistance or death were notified among these patients.

A 42-year old housewife presented herself with flu symptoms and dry cough. Because of pregnancy test (chest x-ray) we accidentally detected a hematuria. Exact medical history revealed the presence of a known IgA-Nephropathy. Banal respiratory infections can exacerbate IgA Nephropathy. In addition, medical history and further investigations are important because of possible secondary IgA-Glomerulonephritis. Treatment of IgA glomerulopathy depends on blood pressure, renal function and degree of proteinuria. An acute renal insufficancy is uncommon (< 5%), but 25% patients develop during 20-25 years a terminal insufficandy.

Sirolimus-associated pulmonary problems are rare but life threatening. Pulmonary problems due to sirolimus treatment are interstitial pneumonitis, bronchiolitis obliterans organizing pneumonia (BOOP), and alveolar hemorrhage. We present a case of sirolimus-related cough in the absence of any pulmonary radiological findings. A 55-year-old man with a history of 4 years of hemodialysis therapy because of end-stage renal disease of unknown etiology underwent cadaveric renal transplantation in June 2006. Three days following the initiation of sirolimus therapy he complained of dry cough and fever. There were no clinical or laboratory findings compatible with specific pulmonary disease. After switching sirolimus to tacrolimus, the cough improved within 1-2 days and resolved in 5 days. Sirolimus should be considered in the differential diagnosis of pulmonary problems in the early posttransplantation period even in the absence of radiological findings.

Type 2 diabetes is reaching epidemic proportions throughout the world, which has major health implications as such patients have considerably increased risk of coronary heart disease (CHD). The renin-angiotensin-aldosterone system (RAAS) is involved in a wide range of adverse effects that contribute to the pathogenesis of CHD in diabetic patients, including vascular haemodynamic regulation, oxidative stress and hypertrophy of vascular cells. Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) are widely used in clinical practice. In diabetic patients ACE inhibitors and ARBs both effectively lower blood pressure, particularly in combination with low-dose thiazide diuretics, and may be considered first line therapies in the treatment of diabetic hypertension. Additionally they have important renoprotective actions independent of their blood pressure-lowering action, which is of particular benefit in diabetic patients, who are at increased risk of developing nephropathy. ARBs are generally well tolerated, but ACE inhibitor therapy is associated with some side effects such as cough and both may result in hyperkalaemia. Blockade of the RAAS with these agents appears to play an important role not only in protecting from renal disease, but it may also help to reduce morbidity and mortality from certain vascular diseases in diabetic patients.

Hypersensitivity to inulin (polyfructan) is a rare event; two cases of food allergy and some patients presenting with allergy and hypersensitivity after inulin infusion have been reported. An 11-year-old boy suffering from severe immunoglobulin (Ig)A nephropathy (IgAN) experienced both anaphylactic reaction and concomitant relapse of his nephropathy following inulin infusion, used for measuring glomerular filtration rate (GFR) 2 years after the appearance of his initial symptoms. Pruritus, wheezing and cough were observed during a first renal function test; results of prick and intradermal tests were negative for inulin. The patient presented with pallor, asthenia and oliguria when a second inulin infusion was performed under dexchlorpheniramine, leading to the immediate cessation of the infusion. He was readmitted 2 days later because of fatigue and nausea related to acute renal failure. A drug-induced acute interstitial nephritis was first suspected. However, due to the presence of macroscopic haematuria and proteinuria, a renal biopsy was performed and showed acute proliferative relapse of IgAN. The underlying mechanism of inulin hypersensitivity is not well known. We can hypothesize that inulin had activated the innate immune system. Inulin may, thus, have been the initiating event of the renal relapse, acting like an infection, in a patient with IgA-mediated immunological dysregulation.

ONTARGET ("ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial") compared the angiotensin converting enzyme inhibitor ramipril (10 mg/day), the angiotensin-receptor blocker telmisartan 80 mg/day, and the combination of the two drugs in 25,620 patients with vascular disease or high-risk diabetes. After a median follow up of 56 months, no significant differences were observed between the three groups neither in the primary composite outcome (death from cardiovascular causes, myocardial infarction, stroke, or hospitalization for heart failure), nor in each of its components, total mortality and other secondary outcomes. Telmisartan was equivalent to ramipril (non inferiority criterion), but was better tolerated (less cough and angioedema). The combination of the two drugs in this population (without congestive heart failure and proteinuric nephropathy) did not bring increased benefit (no superiority), but was associated with more adverse events (hypotension, syncope and renal dysfunction). In this population, the choice of the molecule in monotherapy remains optional and the use of a dual blockade is not justified in order to have a better cardiovascular protection.
