Ocorrência de carcinoma espinocelular labial não melanocítico em usuários crônicos de hidroclorotiazida / Occurrence of non-melanoma labial squamous cell carcinoma in chronic users of hydrochlorothiazide

Diversos autores desenvolveram estudos acerca da potencial associação entre a etiocarcinogênese do carcinoma espinocelular não melanocítico (CECNM) labial e o uso crônico da hidroclorotiazida (HCTZ). Objetivo: A atual revisão objetivou investigar a relação do diurético HCTZ e o risco de CECNM labial. Métodos: Realizou-se uma revisão de literatura nas bases de dados LILACS, PUBMED/MEDLINE e Periódico CAPES, em que foram incluídos artigos em inglês, português e francês, publicados no período de 2017 a 2022. Foram propostos 60 documentos e, dentre esses, 30 foram selecionados para compor a amostra no estudo. Resultados: Foi evidenciada uma relação entre o uso da HCTZ e a ocorrência de CENM com relação dose cumulativa devido às alterações provocadas pelo fármaco, no entanto, em virtude da heterogeneidade de desenhos metodológicos e concentração dos estudos em populações semelhantes, existem limitações quanto à confiabilidade dessas informações. Conclusão: Identificou-se uma desproporção entre a ocorrência e relevância do CENM e a produção científica vigente, demonstrando a necessidade de estudos com metodologias padronizadas que abranjam diferentes especificidades socioeconômicas e demográficas.(AU)

Several authors have developed studies about a potential association between the etiocarcinogenesis of non-melanocytic lip squamous cell carcinoma (NMSCC) and the chronic use of hydrochlorothiazide (HCTZ). Objective: The current study aimed to investigate the relation between the diuretic HCTZ and the risk of lip NMSCC. Methods: A literature review was carried out in the LILACS, PUBMED/MEDLINE and CAPES Periodical databases, which included articles in English, Portuguese and French, published between 2017 and 2022. Sixty documents were collected and, among these, 30 were selected to compose the sample in the study. Results: There was evidence of a relationship between the use of HCTZ and the occurrence of MSCC with a cumulative dose relationship due to changes caused by the drug, however, because of the heterogeneity of methodological designs and concentration of studies in similar populations, there are limitations regarding the reliability of this information. Conclusion: A disproportion between the occurrence and relevance of the NMSCC and the current scientific production was identified, demonstrating the need for studies with standardized methodologies that cover different demographic socioeconomic specificities.(AU)

Bilateral fracture of the shoulders following epileptic seizures: a case report / Fratura bilateral de ombros após convulsões epilépticas: relato de caso

Convulsive seizures caused by hyponatremia occur when this condition is severe and develops quickly, resulting in a brain's adaptive inability to contain brain swelling. Seizures are rarely the cause of shoulder fractures. This is a case report of bilateral humerus fracture following a single epileptic seizure caused by drug hyponatremia, an unconventional event in medical practice. A 69-year-old woman was admitted to the emergency room after a single tonic-clonic seizure with spontaneously ceased sphincter relaxation, showing Glasgow 6. No falls or restraint were reported by observers. When alert, the patient reported pain and difficulty moving both arms. During examination, the movement was li- mited to the right and left. Anteroposterior radiographs revealed bilateral fracture at the neck of humerus. To complement inves- tigation for further lesions, a computed tomography confirmed bilateral fracture-dislocation with impaction of the humeral head with the glenoid. Atraumatic bilateral fracture-dislocation of the humerus after epileptic seizure is a very rare event. It is believed that some of these diagnoses have been neglected due to the difficulty of characterizing the patient's pain in a postictal state. The importance of a detailed physical examination shall be emphasized in risk groups such as the polymedicated elderly.

Uso inapropiado de diuréticos: Algunas características no tan conocidas / Diuretic misuse: Some not so well known characteristics

Entre las situaciones asociadas al uso inapropiado de diuréticos se encuentran los intentos por descencer rápidamente de peso, comunes en los desordenes de la alimentación, y los intentos por enmascarar el consumo de otras sustancias, en el caso de las competencias deportivas. El uso sin indicación ni supervisión médica de estos fármacos genera un desbalance electrolítico, que puede manifestarse con hiponatremia, hipocalemia, hipocalcemia e hipomagnesemia, hipercalemia, entre otras alteraciones. El objetivo de este trabajo fue investigar las caracteríscas del uso inapropiado de diuréticos a partir de la casuística del CENATOXA. Se realizó un estudio descriptivo restrospectivo sobre los análisis ingresados al CENATOXA con solicitud de investigación cualitativa de diuréticos en orina, entre los años 2002 y 2016. En dicho período ingresaron al CENATOXA 138 casos, de los cuales el 56 % resultó positivo para algún diurético. Del total de casos con resultado positivo, el 93,5 % fueron mujeres entre 25 y 55 años de edad y predominó la etiología intencional. Los diuréticos mayoritariamente encontrados fueron hidroclorotiazida y furosemida. El perfil de diuréticos hasta el año 2008 (hidroclorotiazida = 68% de los casos positivos) se diferenció del hallado entre 2009 y 2016 (furosemida + hidroclorotiazida = 60% de los casos positivos). Se observó recurrencia en el uso inapropiado en el 8% de los casos. El uso simultáneo de más de un diurético y la recurrencia son factores que pueden contribuir a la aparición de toxicidad. Estos resultados sugieren que el uso inapropiado de diuréticos es una situación que debería ser ob­servada más atentamente para establecer mejor su alcance y sus riesgos.

Among the situations associated with diuretics misuse are the attempts to lose weight fast, frequently observed in eating disorders, and the attempts to mask the consumption of other substances, in the case of sports competitions. The use of these drugs with no medical indication or supervision generates an electrolyte imbalance, leading to hyponatremia, hypokalemia, hypocalcemia and hypomagnesemia, hyperkalemia, among other alterations. The objective of this work was to investigate the characteristics of diuretics misuse from the CENATOXA database, where the qualitative investigation of diuretics in urine is per­formed. A descriptive retrospective study was conducted on the cases admitted to the CENATOXA with a request for qualitative diuretic investigation, between 2002 and 2016. During this period, 138 urine samples were received at the CENATOXA and 56% were positive for at least one diuretic. Of all cases with positive results, 93.5% were women between 25 and 55 years of age, and intentional etiology predominated. The most detected diuretics were hydrochlorothiazide and furosemide. The diuretic misuse pattern detected up to 2008 (hydrochlorothiazide = 68% of positive cases) differed from that detected between 2009 and 2016 (furosemide + hydrochlorothiazide = 60% of positive cases). Recurrence in misuse was observed in 8% of the cases. The simul­taneous misuse of more than one diuretic and the recurrence are factors that can contribute to the onset of toxicity. These results suggest that diuretic misuse is a situation that should be observed more closely to better assess its consequences and its risks.

Edema pulmonar agudo no cardiogénico secundario a hidroclorotiazida: reporte de un caso y revisión de la literatura / Hydrochlorothiazide induced non-cardiogenic acute pulmonary edema: a case report

Las tiazidas son fármacos frecuentemente usados en la terapia de la hipertensión arterial. Las reacciones adversas de riesgo vital como shock y edema pulmonar agudo son raros. Comunicamos el caso de una mujer de 55 años de edad atendida en Hospital de Puerto Montt, quien tras dos horas de ingerir hidroclorotiazida presentó disnea. Los exámenes de laboratorio generales e imágenes muestran cuadro concordante con edema pulmonar agudo no cardiogénico. Además de la suspensión del fármaco, se realizó soporte hemodinámico y ventilatorio no invasivo, evidenciándose resolución del cuadro a las 48 h. La paciente fue dada de alta 3 días después de su ingreso sin sintomatología.

Thiazides are drugs often used in management of high arterial blood pressure. Shock and acute pulmonary edema are rarely described as adverse reactions related to this drug. We report the case of a 55 years-old woman admitted at Hospital de Puerto Montt, Chile. Two hours after having her first dose of hydrochlorothiazide she presented dyspnea. Laboratory tests and images support the diagnosis of non-cardiogenic pulmonary edema. Resolution of her clinical picture was observed 48 hours after hydrochlorothiazide administration was discontinued and hemodynamic and non invasive ventilation support were supplied. The patient was discharged without symptoms, 3 days after entering to hospital.

Edema pulmonar agudo por hidroclorotiazida: una reacción adversa poco conocida / Hydrochlorothiazide-induced acute pulmonary edema: a rare adverse reaction

In Chile, hydrochlorothiazide is frequently prescribed as first line antihypertensive therapy. Among it’s well known adverse reactions are: electrolytic disorders, hyperuricemia, dyslipidemia, agranulocytosis and azotemia. Acute pulmonary edema is a rare and potentially lethal adverse effect. Only 50 cases have been reported since 1968. In this article, we discuss a case of a 70 year old woman who, one hour after the ingestion of hydrochlorotiazide, presented acute and progressive dyspnea. Her clinical and radiologic findings are compatible with non-cardiogenic acute pulmonary edema.

En Chile, la hidroclorotiazida se utiliza ampliamente como terapia de primera línea en la hipertensión arterial esencial. Entre los efectos adversos más conocidos destacan: trastornos hidroelectrolíticos, hiperuricemia, dislipidemia, azotemia, entre otros. El edema pulmonar agudo es un efecto adverso infrecuente y potencialmente grave. Desde 1968, se han reportado 50 casos clínicos en la literatura. En este artículo presentamos el caso clínico de una mujer de 70 años atendida en el Hospital Santiago Oriente quien, una hora posterior a la ingesta de hidroclorotiazida, presenta disnea aguda progresiva. El estudio clínico y radiológico es compatible con edema pulmonar agudo no cardiogénico.

An economic evaluation of antihypertensive therapies based on clinical trials

OBJECTIVE: Hypertension is a major issue in public health, and the financial costs associated with hypertension continue to increase. Cost-effectiveness studies focusing on antihypertensive drug combinations, however, have been scarce. The cost-effectiveness ratios of the traditional treatment (hydrochlorothiazide and atenolol) and the current treatment (losartan and amlodipine) were evaluated in patients with grade 1 or 2 hypertension (HT1-2). For patients with grade 3 hypertension (HT3), a third drug was added to the treatment combinations: enalapril was added to the traditional treatment, and hydrochlorothiazide was added to the current treatment. METHODS: Hypertension treatment costs were estimated on the basis of the purchase prices of the antihypertensive medications, and effectiveness was measured as the reduction in systolic blood pressure and diastolic blood pressure (in mm Hg) at the end of a 12-month study period. RESULTS: When the purchase price of the brand-name medication was used to calculate the cost, the traditional treatment presented a lower cost-effectiveness ratio [US$/mm Hg] than the current treatment in the HT1-2 group. In the HT3 group, however, there was no difference in cost-effectiveness ratio between the traditional treatment and the current treatment. The cost-effectiveness ratio differences between the treatment regimens maintained the same pattern when the purchase price of the lower-cost medication was used. CONCLUSIONS: We conclude that the traditional treatment is more cost-effective (US$/mm Hg) than the current treatment in the HT1-2 group. There was no difference in cost-effectiveness between the traditional treatment and the current treatment for the HT3 group.

To study the efficacy of losartan on urinary uric acid excretion in thiazide induced hyperuricemic and hypertensive patients

The precise relationship of Hyperuricemia found in hypertensive patients is still obscure; this study is a urinary uric acid lowering intervention with Losartan in hypertensive patients induced by Thiazide diuretics. A number of pharmacological agents like loop diuretics, similarly low doses of aspirin [<3g daily] aggravate Hyperuricemia. The effect of Losartan on urinary uric acid excretion In Hypertensive patients with Thiazide induced Hyperuricemia were investigated in the Department of pharmacology and therapeutics, Basic Medical Sciences Institute Jinnah Postgraduate Medical Centre Karachi. It was randomized, open label, prospective, comparative study. Total 60 hypertensive Hyperuricemic patients were enrolled one by one in this study, selected from medical OPD and wards of Jinnah Postgraduate Medical Centre, Karachi. Patients were divided in three groups. Group-1 patients were treated with Thiazide 50 mg/day, Group-2 with Losartan + Thiazide 50 mg/day, and Group-3 with Losartan 50 mg/day. The effect on urinary uric acid level was measured, after every fortnightly. Treatment with Thiazide + Losartan group and Losartan group showed significantly increase in urinary uric acid excretion. Whereas, Thiazide group decrease in urinary uric acid level. In contrast to Thiazide and Losartan alone Thiazide + Losartan led to a greater increased in urinary uric acid excretion. The average percentage increase in urinary uric acid excretion in Thiazide + Losartan group was -13.27% and the average percentage increased in urinary uric acid excretion was 6.7% in Losartan group. Thus it can be concluded from the present study that urinary uric acid excretion was more increased in combination therapies. Ultimately Losartan decrease serum uric acid level and uricosuric effect of Losartan might be particularly useful in Hyperuricemic patients those on Thiazide diuretic [for hypertension and heart failure]

Acute-Onset Bilateral Myopia and Ciliochoroidal Effusion Induced by Hydrochlorothiazide

The authors experienced two cases of hydrochlorothiazide (HCTZ)-induced acute-onset bilateral myopia and shallowing of the anterior chambers. Two middle-aged women taking HCTZ, a sulfa derivative, visited our clinic complaining of acute bilateral visual deterioration. Both had good visual acuity without corrective lenses before taking HCTZ. A complete ophthalmologic examination revealed bilateral myopic shift, intraocular pressure elevation, shallowing of the anterior chambers, choroidal effusions, radiating retinal folds, and conjunctival chemosis. Approximately one week after HCTZ discontinuance, all ocular changes disappeared completely. Physicians should be aware of the adverse ocular effects of HCTZ and should manage patients accordingly.

A associação captopril-hidroclorotiazida é um esquema anti-hipertensivo bastante utilizado, sendo assim conhecer sua tolerabilidade é de fundamental importância. Objetivos: Mostrar a incidência de efeitos colaterais relacionados à associação e identificar os motivos que levam os pacientes ao abandono ou à troca da associação. Métodos: Estudo transversal realizado no período de junho/2008 a agosto/2009, incluindo 75 pacientes hipertensos que faziam uso da associação (Grupo A) e 52 pacientes que já tinham feito uso, mas que não o faziam mais (Grupo B), coletando-se os dados através de questionários para cada grupo. Resultados: No Grupo A, a maioria dos pacientes era do sexo feminino: 53 (70,6 por cento). Observou-se neste grupo que 20 (26,6 por cento) pacientes apresentavam pelo menos um efeito colateral. Verificou-se que 30,1 por cento das mulheres que usaram a associação e 18,8 por cento dos homens tiveram efeitos colaterais. No Grupo B, os principais motivos relatados para abandono...

Tratamento da hipertensão arterial com olmesartana medoxomila em escalonamento / Based treatment algorithm for essencial hypertension with olmesartan medoxomil

FUNDAMENTO: As diretrizes nacionais e internacionais enfatizam a importância do tratamento eficaz da hipertensão arterial. Apesar disso, verificam-se baixos índices de controle e alcance das metas preconizadas, indicando que é importante planejar e implementar melhores estratégias de tratamento. OBJETIVO: Avaliar a eficácia de um tratamento, em escalonamento de doses, tendo como base a olmesartana medoxomila. MÉTODOS: Este é um estudo aberto, nacional, multicêntrico e prospectivo, de 144 pacientes com hipertensão arterial primária nos estágios 1 e 2, virgens de tratamento ou após período de washout de duas a três semanas para aqueles em tratamento ineficaz. Avaliou-se o uso da olmesartana medoxomila num algoritmo de tratamento, em quatro fases: (i) monoterapia (20 mg), (ii-iii) associada à hidroclorotiazida (20/12,5 mg e 40/25 mg) e (iv) adição de besilato de anlodipino (40/25 mg + 5 mg). RESULTADOS: Ao fim do tratamento, em escalonamento, 86 por cento dos sujeitos de pesquisa alcançaram a meta de pressão arterial (PA) < 130/85 mmHg. Ocorreram reduções na pressão arterial sistólica (PAS) e na pressão arterial diastólica (PAD) de, no máximo, -44,4 mmHg e -20,0 mmHg, respectivamente. A taxa dos respondedores sistólicos (PAS > 20 mmHg) foi de 87,5 por cento e diastólicos (PAD > 10 mmHg) de 92,4 por cento. CONCLUSÃO: O estudo se baseou em um esquema de tratamento semelhante à abordagem terapêutica da prática clínica diária e mostrou que o uso da olmesartana medoxomila, em monoterapia ou em associação a hidroclorotiazida e anlodipino, foi eficaz para o alcance de meta para hipertensos dos estágios 1 e 2.

BACKGROUND: The national and international guidelines emphasize the importance of the effective treatment of essenssial hypertension. Nevertheless, low levels of control are observed, as well as low attainment of the recommended goals, indicating that it is important to plan and implement better treatment strategies. OBJECTIVE: To evaluate the efficacy of a based treatment algorithm with olmesartan medoxomil. METHODS: This is an open, national, multicentric and prospective study of 144 patients with primary arterial hypertension, stages 1 and 2, naïve to treatment or after a 2-to-3 week washout period for those in whom treatment was ineffective. The use of olmesartan medoxomil was assessed in a treatment algorithm divided into 4 phases: (i) monotherapy (20 mg), (ii-iii) associated to à hydrochlorothiazide (20/12.5 mg and 40/25 mg) and (iv) addition of amlodipine besylate (40/25 mg + 5 mg). RESULTS: At the end of the phased-treatment, 86 percent of the study subjects attained the goal of BP < 130/85 mmHg. Maximum reductions in SAP and DAP were -44.4 mmHg and -20.0 mmHg, respectively. The rate of systolic responders (SAP > 20 mmHg) and of diastolic responders (DAP > 10 mmHg) was 87.5 percent and 92.4 percent, respectively. CONCLUSION: The study was based on a treatment regimen that was similar to the therapeutic approach in daily clinical practice and showed that the use of olmesartan medoxomil in monotherapy or in association with hydrochlorothiazide and amlodipine was effective in the attainment of the recommended goals for hypertension stage 1 and 2 hypertensive individuals.

Edema pulmonar agudo por uso de tiazidas, ¿existe falla cardíaca?: Comunicación de un caso / Thiazide induced acute pulmonary edema: Report of one case

Acute pulmonary edema caused by thiazides is uncommon and of difficult diagnosis. It is considered an idiosyncratic reaction and the physiopathology or cardiac function changes are not well known. We report a 60 year-old female with a thiazide induced acute pulmonary edema who was followed with serial measurements of type B n-terminal natriuretic peptide fraction as marker for cardiac dysfunction. There was a significant elevation of the peptide, not associated to evidences of ventricular dysfunction. Its normalization paralleled the resolution of the clinical picture.

La hiperuricemia es un marcador del umbral anaeróbico en la insuficiencia cardíaca crónica / Hyperuricemia is a marker for anaerobic threshold in chronic cardiac failure

Background: Patients with chronic cardiac failure often have elevated plasma uric acid levels, that are associated to a dismal prognosis. Aim: To investigate possible metabolic mechanisms to explain elevated uric acid levels in these patients. Patients and methods: Eighteen patients with chronic cardiac failure aged 61 ñ 10 years old, without gout or renal failure and not using high doses of diuretics (equal or less than 80 mg/day furosemide or 50 mg/day hydrochlorothiazide) were studied. Plasma uric acid levels were correlated with anaerobic threshold, maximal oxygen uptake, plasma noradrenaline and creatinine and left ventricular ejection fraction, measured radioisotopically. Results: Mean maximal oxygen uptake was 16.6 ñ 4.2 ml/kg/min. There was a negative correlation between uric acid levels and maximal oxygen uptake or maximal oxygen uptake/body surface area (r=0.521 and -0.533 respectively, p<0.05). Patients with uric acid levels over 7 mg/dl had a lower anaerobic threshold than patients with lower levels (9.81 ñ 2.41 and 13.08 ñ 3.28 ml/kg/min respectively, p<0.05). No significant differences in maximal oxygen uptake were observed in these two groups of patients (15.5 ñ 4.24 and 18.08 ñ 3.86 ml/kg/min respectively). Uric acid levels did not correlate with plasma noradrenaline, creatinine or lefi ventricular ejection fraction. Conclusions: These results suggest that a defect in cellular oxygenation contributes to the elevation of plasma uric acid levels in patients with chronic cardiac failure

Hiponatremia e hipokalemia graves, recientes, asociadas a hidroclorotiazida, enalaprila y citalopram: caso clínico / Severe and recent hyponatremia and hypokalemia associated to the use of hydrochlorothiazide, enalapril and cytalopram: clinical case

We report a 72 years old hypertensive female, treated with enalapril 10 mg/day and hydrochlorothiazide 25 mg/day during three years. She presented a depressive disorder and cytalopram was prescribed in a dose of 10 mg/day. Two weeks before admission, a serum electrolyte analysis disclosed normal results and the cytalopram dose was increased to 20 mg/day. The patient was admitted with a hyponatremic encephalopathy with a plasma sodium of 100 mEq/L and a plasma potassium of 2.0 mEq/L. cytalopram, enalapril and hydrochlorothiazide were discontinued, hypertonic NaCl and KCl were administered. The patient had a favorable evolution with a remarkable improvement of her symptoms

Captopril associado a didroclorotiazida no tratamento da hipertensäo leve e moderada / Association of captopril and hydrochlorothiazide in mild and moderate hypertension. A Brazilian multicenter study

Objetivo - Avaliar a eficácia e tolerabilidade da associação de captopril 50mg com hidrocloratiazida 25 mg em hipertensos com pressão arterial diastólica (PAD) entre 95 e 115mmHg. Métodos - Estudo aberto, multicêntrico, não comparativo. Na fase inicial, durante 2 semanas, os pacientes receberam placebo, seguida de ½ comprimido da associação. Os pacientes foram avaliados após 4,8 e 12 semanas. Após 8 semanas de tratamento, naqueles em que a PAD foi >90mmHg, foi prescrito um comprimido/dia. Resultados - Foram analisados 433 pacientes, com idades de 47+10 anos, sendo 30 por cento mulheres e 76 por cento brancos. As pressões sistólica/diastólica iniciais foram de 156+16/103+11 mmHg, após 14 dias de placebo, 156+15/103+9 mmHg (p>0,05) e, após 4,8 e 12 semanas, mostraram progressiva redução (p<0,05) para 143+14/95+11, 140+13/91+9 e 134+11/86+8 mmHg. O controle pressórico foi observado em 45, 67 e 88 por cento (p<0,05), após 4,8 e 12 semanas. Tosse foi o sintoma mais importante registrado em 7 por cento dos pacientes em placebo e 12 por cento nos que usavam a associação. A tolerabilidade foi considerada boa por 98 por cento dos pacientes. Conclusão - A associação de captopril com hidroclotiazida é eficaz e tem boa tolerabilidade, sendo prescrita em dose única diária em monoterapia, para hipertensos leves e moderados.

Edema pulmonar agudo asociado a hidroclorotiazida / Acute pulmonary edema associated to hydrochlorotiazide

Hydrochlorotiazide may cause pulmonary edema. We report 2 female patients aged 58 and 69 years old, who after the ingestion of this diuretic, were admitted to an intensive care unit with fever, digestive symptoms, severe dyspnea, hypotension and a hemodynamic pattern resembling hypovolemia. Both had a good response to volume repletion and vasoactive drugs. Despite the severity of the clinical picture, they had a full and fast recovery. This type of reaction to hydrochlorotiazide is probably idiosyncratic and must be considered in the differential diagnosis of pulmonary edema

Edema pulmonar no-cardiogénico relacionado con la hidroclorotiazida / Non-cardiogenic pulmonary edema related to hidrochlorothiazide

A 54 years old female patient with a mitral valve prolapse and a rheumatic arthritis with steroids was admitted with dysnea and hypotension, that started 30 min after taking a pill containing enapril and hydroclorothiazide. Hemodynamic monitoring with a Swan-Ganz catheter showed a pulmonary capillary pressure of 5 mm Hg, a systemic vascular resistance of 887 (dyn sec)/cm5 and a cardiac output of 10 1/min. Tha patient had a history of adverse reactions to thiazides and responded to volume replacement, dopamine and steroids
