Presentación atípica de molusco contagioso: compromiso ocular bilateral en paciente con VIH / Atypical presentation of molluscum contagiosum: bilateral ocular involvement in a patient with HIV

La infección por molusco contagioso (MC) en adultos se asocia frecuentemente a transmisión sexual y/o inmunodepresión, por ejemplo, por VIH. En este grupo, la manifestación clínica suele ser atípica. A continuación, se presenta el caso de un paciente con diagnóstico de VIH, bajo recuento de CD4 y carga viral elevada que consulta por múltiples MC en genitales, tronco, cara y ojos además de conjuntivitis en ojo derecho. Se mantuvo terapia antirretroviral (TARV) y se indicó tratamiento para conjuntivitis. La infección por MC en pacientes con VIH se asocia a etapas SIDA con un aumento de los casos a menor recuento de linfocitos CD4, generalmente menor a 200 cel/mL. La pobre respuesta inmune celular de estos pacientes explica su comportamiento clínico atípico. Este grupo presenta una mayor mortalidad que el de pacientes seropositivos sin MC, lo que se explica por la mayor inmunosupresión asociada. El diagnóstico es clínico, aunque podría verse entorpecido cuando hay compromiso ocular por la presencia de lesiones atípicas que hacen necesario considerar diversos diagnósticos diferenciales. El tratamiento es controversial y tiende a existir una baja respuesta y recidiva frente a terapias convencionales en pacientes con VIH cuando la inmunosupresión es marcada por el recuento CD4 muy bajo. La TARV pareciera ser la mejor alternativa para su tratamiento, sin embargo, es importante considerar posibles complicaciones asociadas, como la instauración de síndrome de restauración inmunológica una vez iniciada. Esto podría traducirse en lesiones oculares graves cuando existe compromiso en este órgano

Molluscum contagiosum (MC) infection in adults is frequently associated with sexual transmission and / or immunosuppression, for example by HIV. In this group, the clinical manifestation is usually atypical. Herein we present the case of a patient with a diagnosis of HIV, a low CD4 count and a high viral load who consulted for multiple MC in the genitals, trunk, face and eyes, as well as conjunctivitis in the right eye. Antiretrovitral therapy (ART) was maintained and treatment for conjunctivitis was indicated. MC infection in HIV patients is associated with AIDS stages with an increase in cases with a lower CD4 lymphocyte count, generally less than 200 cells / mL. The poor cellular immune response of these patients explains their atypical clinical behavior. This group presents a higher mortality than that of seropositive patients without MC, which is explained by the greater associated immunosuppression. The diagnosis is clinical, although it could be hampered when there is ocular compromise due to the presence of atypical lesions that make it necessary to consider various differential diagnoses. Treatment is controversial and there tends to be a poor response and relapse to conventional therapies in patients with HIV when immunosuppression is marked by a very low CD4 count. ART seems to be the best alternative for its. However, it is important to consider possible associated complications such as the onset of immune restoration syndrome once it has been started. This could translate into serious eye injuries when this organ is compromised

Comparative study on the efficacy of non-steroidal, steroid and non-use of anti-inflammatory in the treatment of acute epidemic conjunctivitis

Abstract Purpose To evaluate the effects of prednisolone against sodium diclofenac both with ciprofloxacin compared to artificial tears on the symptoms and signs of acute viral conjunctivitis. Methods Study included 37 patients diagnosed with acute conjunctivitis and distributed by three groups: A (1% prednisolone acetate + ciprofloxacin (0.3%); B (Sodium diclofenac (0.1%) + ciprofloxacin (0.3%) and C (artificial tears + ciprofloxacin (0.3%). Patients received medication 6/6 hours daily. Signs and symptoms (e.g. lacrimation, burning, photophobia, etc.) were scored at baseline and on the first, third, fifth and seventh days and in the end of treatment using a standardized questionnaire and slit lamp anterior segment examination. Results All three groups demonstrated an improvement in the signs and symptoms of conjunctivitis in their follow-up visits. There was no significant difference in symptom and sign scores between Group A and B and B and C in the study visits ( p >0.05). However, the comparison between groups A and C showed a clinical trend (p=0.05) on third evaluation suggesting better clinical action using the corticosteroids. Conclusion The prednisolone acetate was not superior to the use of sodium diclofenac or artificial tears in relieving the signs and symptoms of viral conjunctivitis.

Artificial tears alone versus 0.45% ketorolac tromethamine with artificial tears for the treatment of acute viral conjunctivitis / Lágrima artificial versus cetorolaco de trometamina 0,45% associado à lagrima artificial no tratamento da conjuntivite viral aguda

Purpose: To evaluate the effects of preservativefree 0.45% ketorolac tromethamine and artificial tears (carboxymethylcellulose) compared with those of preservativefree artificial tears alone on the symptoms and signs of acute viral conjunctivitis. Methods: This was a randomized, doublemasked clinical trial that included 50 patients who were diagnosed with acute viral conjunctivitis and distributed into two groups (Group 0: artificial tears and Group 1: 0.45% ketorolac tromethamine + carboxymethylcellulose). The patients were instructed to use the medication 4 times daily. Signs (conjunctival hyperemia, chemosis, follicles, and secretion) and symptoms (general ocular discomfort, itching, foreign body sensation, tearing, redness, and swelling of the eyelids) were scored at baseline and on the third and seventh days of treatment using a standardized questionnaire and slitlamp anterior segment examination. Results: Both groups showed an improvement in the signs and symptoms of conjunctivitis in their follow-up visits. There was no significant difference in symptom and sign scores between Group 0 and Group 1 in the study visits (p>0.05). The frequency of side effects during treatment was similar between groups (p>0.05). Conclusions: Our findings indicate that 0.45% ketorolac tromethamine was not superior to the use of artificial tears in relieving the signs and symptoms of viral conjunctivitis. .

Objetivo: Avaliar o efeito do colírio de cetorolaco de trometamina 0,45% associado à carboximetilcelulose sem conservante em comparação ao uso isolado de lágrimas artificiais sem conservantes nos sinais e sintomas da conjuntivite viral aguda. Métodos: Ensaio clínico duplo-mascarado randomizado incluindo 50 pacientes com diagnóstico de conjuntivite viral aguda, distribuídos em dois grupos (Grupo 0: lágrimas artificiais e Grupo 1: cetorolaco 0,45% + carboximetilcelulose). Os pacientes foram orientados a utilizar a medicação quatro vezes ao dia. Sinais (hiperemia conjuntival, quemose, folículos e secreção) e sintomas (desconforto ocular geral, prurido, sensação de corpo estranho, lacrimejamento, vermelhidão e inchaço de pálpebras) foram avaliados na consulta inicial, no terceiro e no sétimo dia de tratamento utilizando um questionário padronizado e biomicroscopia de segmento anterior. Resultados: Ambos os grupos apresentaram melhora dos sinais e sintomas de conjuntivite nas visitas de reavaliação. Não foi observado diferença estatística na mudança dos escores dos sinais e sintomas entre o Grupo 0 e o Grupo 1 durante as visitas do estudo (p>0.05). A frequência de efeitos colaterais durante o tratamento foi similar entre os dois grupos (p>0.05). Conclusão: O uso do cetorolaco de trometamina 0,45% não se mostrou superior ao uso isolado de lágrimas artificiais no alívio dos sinais e sintomas da conjuntivite viral. .

Uso de ganciclovir 0,15 por cento gel para tratamento de ceratoconjuntivite adenoviral / Ganciclovir 0.15 percent ophthalmic gel in the treatment of adenovirus keratoconjuntivitis

OBJETIVOS: Determinar a efetividade e a toxicidade do ganciclovir 0,15 por cento gel no tratamento de ceratoconjuntivites adenovirais e na prevenção de complicações tais como infiltrados corneanos, membranas ou pseudomembranas conjuntivais. MÉTODOS: Ensaio clínico duplo-cego, intervencionista, randomizado. Os 33 pacientes com diagnóstico clínico de ceratoconjuntivite adenoviral com início dos sintomas há menos de cinco dias foram randomizados em dois grupos: Grupo 1 (tratamento) com 19 pacientes que usaram ganciclovir e Grupo 2 (controle) com 14 pacientes que usaram lágrima artificial sem conservante. Todos pacientes responderam a um questionário de sinais e sintomas e foram submetidos a um exame oftalmológico. No 6º dia de tratamento responderam ao mesmo questionário por telefone e no 10º dia foram reavaliados pelo mesmo examinador e responderam novamente ao questionário. Os sinais e sintomas foram comparados. Para análise estatística foi utilizado os testes T de Student, Mann-Whitney e Wilcoxon, com significância estatística p<0,05. RESULTADOS: Tendência de melhor resposta no grupo tratamento em relação à percepção pelos pacientes, além da melhora mais rápida desse grupo em relação ao grupo controle (p=0,26). Houve menor transmissão para o olho adelfo (p=0,86) e para pessoas do convívio (p=0,16) no grupo tratamento. Comparando os dois grupos não houve diferença estatística em relação aos sintomas e sinais da conjuntivite. Comparando isoladamente cada grupo entre o pré-tratamento e no decorrer do tratamento, observou-se melhora estatisticamente significativa da dor, prurido e fotofobia apenas no grupo tratamento. Ganciclovir não mostrou toxicidade e teve maior tolerância pelos pacientes. Não houve diferença significativa no aparecimento de complicações da conjuntivite entre os dois grupos. CONCLUSÕES: O estudo evidenciou uma tendência à melhora mais rápida dos sinais e sintomas dos pacientes tratados com ganciclovir em relação ao grupo ...

PURPOSE: To evaluate the efficacy and the toxicity of 0.15 percent ganciclovir gel in the treatment of adenoviral conjunctivitis and in preventing ocular complications after adenoviral conjunctivitis, such as corneal infiltrates and pseudomembranes. METHODS: Double blind, interventional and randomized clinical trial. Thirty-three patients with clinical diagnosis of adenoviral conjunctivitis with onset of symptoms for five or less days were randomized in two groups: Group 1 (treatment) with 19 patients used ganciclovir gel and Group 2 (control) with 14 patients used artificial tears without preservative. Patients answered a questionnaire of signs and symptoms and were submitted to an ophthalmologic exam. On the 6th and 10th days of treatment they answered the same questions and were re-examined by the same ophthalmologist. Signs and symptoms were compared. T Student, Mann-Whitney e Wilcoxon tests were used to statistical analysis. RESULTS: Trend of better response in the treatment group in relation of patients' perception, besides faster improvement of this group compared to the control group (p=0.26). There were lower transmission to the fellow eye (p=0.86) and to people living together (p=0.16) in the treatment group. No statistical difference related to signs and symptoms of conjunctivitis were found comparing both groups. We observed statistical difference in pain, itch and photophobia only in the treatment group, comparing each group alone. No toxicity and more tolerance of the ganciclovir were observed. There was no statistical difference in the ocular complications after conjunctivitis between both groups. CONCLUSIONS: This study showed trend of better and faster response of the signs and symptoms of the patients treated with ganciclovir compared with the control group, but with no statistical significant. These results need to be confirmed by additional studies, with more patients and longer follow-up. Clinical Trails.gov: NCT01349452.

Self-medication: initial treatments used by patients seen in an ophthalmologic emergency room

OBJECTIVE: This study seeks to identify practices of self-medication in the treatment of ocular emergencies. We examine patients' use of both homemade preparations and manufactured products before seeking specialized care. MATERIALS AND METHODS: We conducted a cross-sectional analytic survey of consecutive patients seen in the ophthalmology emergency room of a teaching hospital. RESULTS: The sample included 561 subjects, 51.3 percent males and 48.7 percent females, with a mean age of 39.8 years. Prior to seeking emergency care, 40.5 percent reported self-medicating; 29.4 percent used a homemade preparation (13.9 percent referred to an industrialized product like boric acid as a homemade preparation), and 11.1 percent used a manufactured product. The most frequently used products included a boric acid solution (53.3 percent), a normal saline solution (35.7 percent), herbal infusions (6.1 percent) and breast milk (4.8 percent). Viral conjunctivitis was the most frequent diagnosis (24.4 percent), followed by the presence of a corneal foreign body (7.4 percent). No significant differences were found in the self-treatment of ocular injuries according to gender (p = 0.95), level of education (p = 0.21) or age (p = 0.14). In addition, self-medication practices were not related to the medically judged severity of the condition. CONCLUSION: Patients often attempt to treat conditions that require ophthalmologic emergency care by self-medicating with homemade or manufactured products. The most widely used products include boric acid, normal saline, leaf infusions and breast milk. This behavior occurs independently of educational level, gender, age or the nature of the ocular condition. Self-medication is a culturally driven practice that is used even in cases of acute ocular injuries.
