Noncardiogenic pulmonary edema is a rare but potentially life-threatening complication of hydrochlorothiazide therapy. We describe three patients who developed this serious adverse reaction. A 64-year-old woman developed dypsnea and hypotension within 60 minutes of taking a single dose of hydrochlorothiazide 25 mg. She was admitted to the critical care unit with acute respiratory failure and subsequent multiple-organ dysfunction. The second patient was a 56-year-old woman who experienced sudden onset of shortness of breath that developed 10 minutes after taking a single dose of hydrochlorothiazide 25 mg. The third was a 59-year-old woman who developed sudden onset of shortness of breath, nausea, vomiting, and diarrhea after her first dose of hydrochlorothiazide-triamterene. All three women had a history of a similar, albeit minor, reaction to a thiazide diuretic. Review of the literature identified 36 additional cases of noncardiogenic pulmonary edema after thiazide use. The patients developed symptoms 10-150 minutes after ingestion of hydrochlorothiazide or another thiazide. Symptoms can occur on first exposure to the drug or in patients taking the drug intermittently. Of interest, 90% of documented cases occurred in women. With the increasing use of thiazide diuretics in the treatment of hypertension, clinicians need to be aware of the possible association of these drugs with the development of noncardiogenic pulmonary edema.
Thiazide-induced lichenoid photosensitivity.

We report the case of a 77-year-old male who developed a florid photosensitive eruption while taking thiazide diuretics for heart failure. The lesions were lichenoid in appearance and this was confirmed histologically. The eruption cleared on withdrawal of the drug. Although thiazide-induced photosensitivity is a well-documented phenomenon, there have been no histologically proven cases of a lichenoid eruption in light exposed areas in the recent literature.

Spectrophotometric and chromatographic (HPLC) methods for determination of hydrochlorothiazide, triamterene and propranolol hydrochloride were elaborated. Both methods were appropriate for the determination of three compounds in pharmaceutical preparations containing their mixtures. Both the elaborated methods for the determination of the studied compounds give comparable results and can successfully be applied to the assay in their mixtures occurring in the composition of pharmaceutical preparations.
Olanzapine-induced diabetic ketoacidosis.

OBJECTIVE: To report the case of a patient taking olanzapine who developed diabetic ketoacidosis (DKA). CASE SUMMARY: A 46-year-old African American woman with no previous history of diabetes mellitus was admitted to the hospital and subsequently diagnosed with DKA and acute pancreatitis. The patient had been taking olanzapine, valproic acid, carbamazepine, hydrochlorothiazide/triamterene, and conjugated estrogens prior to admission. Olanzapine was the last medication added to the regimen. In addition to clinicians treating the DKA with appropriate interventions, olanzapine (due to possible association with hyperglycemia and DKA) as well as valproic acid (due to possible association with pancreatitis) were discontinued from the medication regimen. The patient was discharged home and her most recent glycosylated hemoglobin and fasting glucose concentrations have been within the normal range. DISCUSSION: Atypical antipsychotics, such as olanzapine, have been associated with hyperglycemia and possibly DKA. We believe that this occurred in our patient who had no previous history of diabetes mellitus. Possible mechanisms of action and potential confounding variables are discussed. CONCLUSIONS: Clinicians should monitor blood glucose concentrations periodically in patients taking olanzapine, especially in those patients with risk factors for diabetes mellitus.

Recombinant human interleukin-11 (rhIL-11), or Neumega rhIL-11 Growth Factor, is a recombinant cytokine that stimulates megakaryocytopoiesis, increases platelet production, and also has shown anti-inflammatory and immune-modulating activity. Mild, reversible anemia was the most common adverse event observed in clinical studies and was demonstrated to be related to hemodilution. The purpose of this study was to examine the renal mechanisms of the rhIL-11-induced volume retention and devise a possible therapeutic intervention to ameliorate this effect. Eighteen healthy volunteers (9 male and 9 female) on a controlled sodium (180 mEq/day) and potassium (120 mEq/day) diet were randomized to one of six treatment sequences in a three-period crossover design. Each subject received 25 micrograms/kg IL-11 s.c. once daily, 25 micrograms/kg IL-11 s.c. once daily + Maxzide-25 twice daily, or placebo for 7 days in a crossover design. There was a 14-day washout period between treatment periods. Renal clearance parameters indicated that mean sodium excretion was decreased compared to placebo within 8 hours after dosing with rhIL-11, with these results reaching statistical significance 8 to 16 hours postdose (p < 0.01). The cumulative sodium excretion (mEq +/- SD) over the 7-day treatment period for each respective treatment group was the following: rhIL-11 = 833 +/- 154, rhIL-11 + Maxzide-25 twice daily = 1114 +/- 178, and placebo = 982 +/- 193 (p < 0.01). Hemoglobin concentration and hematocrit values, used as indicators of hemodilution, decreased in the rhIL-11-treated group as compared to the baseline and placebo groups (p < 0.01). Concurrent dosing with Maxzide-25 twice daily reduced the rhIL-11-associated hemodilution by about 50%.

OBJECTIVE: To establish reliability and ease of use of the Cambridge Neuropsychological Test Automated Battery (CANTAB) in assessing changes in cognitive function induced by antihypertensive drugs. DESIGN AND METHODS: Standard neuropsychological testing was combined with CANTAB in a double-blind 18-week cross-over study in elderly hypertensives taking perindopril or hydrochlorothiazide/triamterene (HT). Cognitive effects were assessed by employing tests of attention, visuospatial and verbal memory, learning, reasoning, planning, problem solving, speed and coordination. Affect was assessed using two different depression-rating scales. RESULTS: Perindopril and the diuretic had no adverse effects on the various aspects of cognitive function. Mood, as assessed by the Hamilton Depression Rating Scale and the Beck Depression Inventory, was improved on Perindopril, and the error rate in the motor screening test was lower. Ambulatory blood pressure monitoring showed both drugs achieved effective 24-h control. CONCLUSIONS: The ease of use and the ability to adjust the level of testing to the requirements of individual patients, together with the reliability of longitudinal test/re-test results, indicates that CANTAB is an important addition to the methods available to quantitate adverse central nervous system drug effects. The other purpose of the study was to assess any adverse cognitive effects of perindopril against a drug HT believed to have no adverse central nervous system effects. In this context, perindopril was free of adverse effects in all the objective tests employed. In addition, there was a benefit seen in two independent assessments of depression (the Hamilton and the Beck rating scales).

Procedures were developed for the simultaneous determination of pharmaceuticals in binary mixtures, containing hydrochlorothiazide-benazepril hydrochloride, hydrochlorothiazide triamterene and hydrochlorothiazide cilazapril by ratio spectra derivative spectrophotometry and Vierordt's method. Mean recoveries, relative standard deviations and linearity ranges in calibration graphs of the methods were compared. These procedures were successfully applied to three pharmaceutical formulations for the determination of active ingredients.

The aim of the study was to compare the antihypertensive efficacy of either felodipine or the diuretic combination hydrochlorothiazide/triamterene in a group (n = 65) of elderly (> or = 70 years) hypertensives (office blood pressure > or = 160/95 mmHg) with special regard to ambulatory blood pressure monitoring, hypertensive heart disease and metabolic parameters. This was a randomized, double-blind study with a treatment period of 6 months. Reduction of office and 24-hr ambulatory blood pressure was comparable with both treatment regimens; after 6 months. 18 of 29 patients in the felodipine group (62%) and 20 of 27 patients in the diuretic group (74%; p = 0.4) were controlled. While episodes of ischemic type ST-segment depression were significantly reduced in the felodipine group (from 49 to 9 episodes), there was no significant change in the diuretic group (from 24 to 21 episodes). Both regimens decreased left ventricular wall thickness, but the decline in left ventricular muscle mass index was significant only for felodipine. Felodipine did not induce any change in metabolic or hormonal parameters; the diuretic combination significantly increased serum creatinine, uric acid, plasma renin activity, and plasma prorenin. Thus, the antihypertensive efficacy of felodipine and the diuretic combination was comparable in elderly hypertensives; only felodipine, however, improved parameters of hypertensive heart disease and showed a neutral metabolic and hormonal profile.

Corinfar-retard as a base of different combinations with triampur, Cordanum, Capoten were studied in 52 patients with stable arterial hypertension (systolic pressure > 180 mm Hg, diastolic pressure > 105 mm Hg). In the above combinations pharmacokinetics of corinfar-retard did not change. Good response was noted in corinfar-retard combination with Cordanum in patients with moderate hemodynamic changes, hypertonicity of sympathoadrenal system, tachycardia. In patients with impaired myocardial contractility, elevated total peripheral vascular resistance, noticeable hypotensive effects was registered in combination with triampur. The absence of hypotensive effect in the above combination required the addition of Capoten which was absolutely indicated in patients with stable increase in plasma renin activity.
